Section III-D: Mounting Accessories to the SpectraPro-300i Slit Assemblies
All ARC accessories come with their own set of instructions for proper mounting and operation. The
instructions below are only general information. Please refer to the individual instructions for detailed
information.

Accessories: The full range of ARC SpectraPro accessories mount directly to the SpectraPro-300i slit
assemblies. A drawing of the standard slit assembly can be found in the Appendices Section to assist you in
mounting of accessories. To mount an accessory to the slit, the general procedure is as follows:
1.

Place the accessory directly against the face of the slit body. Light sources normally mounton the entrance slit, detectors on the exit slit. Other accessories such as fiber bundles
normally mount on the entrance slit, but are also compatible with the exit slit.

2.

Using four (4) 8-32 screws normally provided with the accessory, secure the accessory to theslit body.

Light sources fitted with light collection/focusing optics are normally factory aligned to the standard slit.

Note: In some instances with light sources, there is limited access to thebottom two screw holes. In this case ARC provides special slottedholes in the light source housing to facilitate mounting of the source
to the slit.
Section III-E: Detector Mounting Instructions: Mounting Focal Plane Detectors to
the SpectraPro-300i Spectrograph

The standard mounting flange for CCDs and diode arrays accommodates detectors with two different bolt
circles. There are three (3) equally spaced #10-32 tapped holes on a 3.60” bolt circle, and three (3) equally
spaced holes on a 3.88” bolt circle designed to accept #10-32 button head screws. A baffle is mounted in
the array detector mounting flange to define the focal plane area. This baffle has two sets of mounting holes
90 degrees apart which permit the mounting to be rotated 90 degrees to accept different array detectors.
To mount an array detector to the SpectraPro-300i, use the following procedure:
1.

The array detector mounting flange has a sliding tube, which fits inside the front plate of theSpectraPro-300i.

NOTE: At this point it is very important to check the focal plane distanceof the array detector. This is the distance from the front mounting
surface of the array detector to the actual CCD or diode arrayelement. Because array detector focal distances vary, the correct
distance is crucial in order to determine if a spacer is required forproper focus. This spacer is provided with spectrographs. If thedetector focal plane distance falls between .67” and 1.00”, then no
spacer is required.

62.

Using a 1/8” allen wrench, loosen the two (2) set screws located at the top and side of thefront plate. Gently slide the array detector mounting flange all the way out of theSpectraPro-300i housing. Make sure that the sliding tube and o-ring are kept clean.

3.

Remove the shipping cover from the sliding tube, and the spacer if not required.

4.

Position the array detector mounting flange against the array detector, and match the holepatterns. When correctly positioned, the baffle aperture orientation should match thedetector array orientation. If it does not align properly, contact ARC.

5.

Fasten the array detector mounting flange to the detector, then carefully slide this assemblyback into the SpectraPro-300i housing.

6.

Tighten the #10-32 set screw on the top of the front plate first, and then tighten the one on
the side.

Section III-F: Slit Width Adjustments in the Model 716 Bilateral Slits
The slit width of each bilateral slit assembly (716 type) is adjustable from 0.010 millimeters to 3
millimeters (10µm to 3,000µm) by a micrometer located on the top of the slit housing. The micrometerknob is graduated in 0.010 millimeter (10µm) increments.
Each clockwise revolution of the micrometer knob increases the slit width 0.25 millimeters (250µm). For
maximum reproducibility, the slit width should be set in a clockwise direction (increasing slit widths)
each time it is changed. Refer to the drawing below.
The micrometer knob should not be rotated below a reading of 0.00 or above 3.00. A micrometer settingof less than 0.010 millimeters (10µm) should not be used, because a stop is provided to prevent the slit
jaws from contacting each other.

Note: Damage May Be Done If Slit Jaws Are Opened Wider Than 3.0mm.

Slit Width Setting: 200 Micrometers (0.200mm)
Slit Width Setting:1380 Micrometers (1.38mm)

Section III-F Continued:

Interchanging Fixed Width Slit Plates in the
Model 715 Fixed Slit Assemblies:

If your SpectraPro-300i was purchased with the Model 715
type fixed slit assemblies, the following procedure should be
used in order to change slit widths. First, at least one
additional fixed slit plate, Model 715-4-XX or 715-14-XX,
must be available to permit changing widths in the 715 typeslit assemblies.

1.875”

Changing Fixed Slit Plates in the 300-715-1
and 300-715-2 Assemblies:
1.

Remove any accessories from the slit body.

2.

Using an allen wrench, loosen the two slit plate screws
which hold the slit plate to the slit body. Remove theslit plate without contacting the slit blades. Store theremoved slit plate in a clean, dry area.

Note:

When correctly mounted, the slits are off-centered height-wise,slightly above the center of the slit body. See the slit assembly
drawing in the appendices section for details, or pictures on thispage for reference.

3.

Place the new slit plate in the slit body and secure
it in position using the slit plate screws. The cone
shaped holes in the slit plate are designed to alignthe slits to the optical system.

4.

The slit width has now been changed.

Section IV-A: Initialization
When power is turned ON to the SpectraPro-300i, it initializes to a wavelength of 0.0nm for grating number
1. If the power is switched OFF and then ON again to the SpectraPro-300i, it will re-initialize. Initialization
gives the system a reference, or starting position to keep track of wavelength position, grating location, andother parameters. Alternative start-up parameters can be programmed if the factory defaults are notsuitable (See Appendix A).

Section IV-B: Using the Optional Model 300-749 Remote Scan Controller
The Model 300-749 is a Remote Scan Controller (referred to as “controller” for the remainder of this manual)for the SpectraPro-300i Monochromator/Spectrographs. Functions include scanning of wavelengths, GOTO
for rapidly moving the monochromator to a specific center wavelength, grating selection, and interchanging
of grating turrets. It consists of an H-P Model HP 48G Graphics Calculator with RS232 interface, and
ARC-written scan control software. The controller is programmed with all the instrument scan functions
displayed as convenient menu items, with simple keystrokes enabling any of the scanfunctions to be performed.
The controller is connected to the SpectraPro-300i through the standard RS232 port with the cableprovided. It is designed to send commands and receive information about the specific SpectraPro-300i it is
attached to, therefore a single controller can be used with many different instruments (one at a time,
however). When the power is switched OFF and then ON again to the SpectraPro-300i and the controller,
the SpectraPro-300i will re-initialize. If the controller power is switched OFF then ON again, and theSpectraPro-300i power is left ON, then the controller will return to the last menu selected.

Battery Power Management Feature:
If the controller is not used for a few minutes, the LCD screen will turn off to savebattery power. If this happens, simply press the ON button to return to the menu youwere using.

Operation of the Controller with the SP-300i:
With the controller connected to the SpectraPro-300i, turn the power ON to both components. After theSpectraPro-300i initializes, the following menu should be displayed:{ HOME }

This menu shows that Grating #1 (1200g/mm, blazed at 500nm) is in the operating position. To selectgrating #2, press the white button under the number 2 on the display. During the 20 seconds required fora grating change, the controller displays “Changing Grating”. When the change is complete, the dot (■)
appears next to the #2 grating. To return back to the Main Menu, press the white key below the QUIT
function. The Main Menu will now display the new grating.
13

TURR (Turret Change) Menu:
The SpectraPro-300i comes with a triple grating turret which accepts 1, 2 or 3 gratings. If more than 3
gratings are required, optional interchangeable turrets are available. If your SpectraPro-300i has beenpurchased with more than one turret (up to three turrets are possible for a total of nine gratings), you must
input the appropriate turret number using the TURR menu each time a turret is changed. For example, if
you switch from turret #1 to turret #2, use the TURR Menu to let the software know you made the change.
This enables the SpectraPro-300i and controller to scan correctly and provide correct wavelength display.
To select the Turret Change Menu from the Main Menu, press the white key below TURR on the controller
display. The TURR menu displays, with a dot (■), which grating turret is currently installed in theSpectraPro-300i, along with available turrets. A display of “Not Inst” means that no gratings have been
installed in the specified turret position. For example, the following menu shows that turret #1 is installedwith Grating #1 (1200g/mm) and Grating #2 (300g/mm). It also shows that turret #2 is available, and that
#3 is not installed. To input the correct turret information, press the white key below the numbers 1, 2, or

JOG Instructions:
The controller for the SpectraPro-300i allows the user to change wavelengths without accessing GOTO or
SCAN, and without keying in a destination wavelength. This function is useful for rapidly scanning fromone wavelength region to another, searching for the peak of a line, or accurately positioning a source image
on an array detector. This function is called JOG, and it can be accessed at any time that the otherfunctions (GOTO, SCAN, etc.) are not in operation. The controller has four direction keys marked witharrow indicators (▲ ,▼, , and). JOG operates by moving the SpectraPro-300i in wavelength increments
ranging from 0.1nm to 1000nm, and also in “single motor step” increments. Pressing the UP arrow ( )increases the JOG increment a factor of 10 each time it is pressed, while the DOWN arrow ( ▼ ) decreases
the increment a factor of 10. To access the single motor step JOG, press the DOWN arrow ( ▼ ) until theincrement setting decreases below 0.1nm.
JOG direction is controlled by the arrow keys marked (and). To JOG to increasing wavelengths (bythe increment chosen), press the () key. To JOG to decreasing wavelengths, press the () key. If youpress either key more than once, the SpectraPro-300i will move the preset JOG increment multiplied by the
number of times the key is pressed. The maximum wavelength possible depends on the grating in theoperating position (1400nm maximum with a 1200g/mm grating, 2800nm maximum with a 600g/mm
grating, etc.). The minimum wavelength possible is -10nm for all gratings.

Section IV-C: Operating the SpectraPro-300i Using a Computer
The Acton Research Corporation SpectraPro Monochromator can be controlled from an RS232 terminal orcomputer using RS232 or IEEE488. The same command set, listed below, is used for both RS232 andIEEE488.
Commands can be sent as single commands or grouped in strings of commands. All commands are single
words (contain no spaces) and all commands in a string are separated by at least one space. Parameters, if
needed, precede the command and are separated from the command by at least one space (e.g. 546.7
GOTO).
For RS232 operation, the port set-up is 9600 baud, 8 data bits, 1 stop bit and no parity. All commands or
strings of commands must be terminated with a carriage return (0D hex). The SpectraPro-300i responds to
a command when the command has been completed by returning the characters OK followed by carriage
return and line feed (hex ASCII sequence 20 6F 6B 0D 0A). The default condition is to echo each character
that is sent to the SpectraPro-300i.
When using the IEEE488 (or GPIB) interface, the default device address is 11. The device address can be
set to any value from 1 to 30 using the command SET-ID. The command ?ID is used to read back the IEEE
address. Each command or string of commands must be terminated with a carriage return (0D hex). Whensending a command or string of commands, it is important to wait for the SpectraPro to complete theprocessing of that command string before sending another command. This is accomplished by checking thestatus byte. The SpectraPro controls bits in the IEEE488 status byte which can be read from the IEEE488
controller. The command for reading this status byte will be unique to your IEEE controller. For example,
with National Instrument controllers, the command is IBRSP. With CEC controllers, the command is
SPOLL.

IEEE488 Status Byte Bits:
Bit 0

0 = command is being processed
1 = SP-300i ready for another command

Section IV-D: Focusing and Alignment of Array Detectors
With the array detector properly mounted to the SpectraPro-300i, use the following procedure to align andfocus the array detector to the SpectraPro-300i optical system. It is assumed that the array detection
system is running for the following procedure.
1.

Mount a light source such as a mercury pen-ray type to the entrance slit of theSpectraPro-300i. ARC offers a standard mercury lamp, Model MS-416, designed for thispurpose. Any light source with line output can be used. If there are no “line” sources
available, it is possible to use a broad band source such as tungsten for the alignment. If
this is the case, use only a wavelength setting of 0.0nm for alignment purposes.

2.

With the SP-300i properly connected to the controller or computer, turn the power ON andmove the spectrograph to a wavelength of 435.8 nm if using a mercury lamp, or 0.0 nm for abroad band source, or another wavelength corresponding to a spectrum produced by another“line” source.

3.

With the array detector operating, check the image of the light source if running in an
imaging mode with a CCD. Otherwise check the line intensity and shape.

4.

Using a 1/8” allen wrench, loosen the two (2) #10-32 set screws (approximately 2 turns)
located on the top and side of the front plate, and slowly slide the array detector IN or OUT
until the sharpest image is achieved, or the sharpest line is achieved.

CAUTION:

The set screws must be loose when turning the thumb wheel
adjustment, or severe damage will occur. The distance between theedge of the array detector mounting flange and the instrument MUSTNOT exceed .33”.

5.

Move the thumb wheel until it just makes contact with the array detector mounting flange.
This enables you to rotate the detector without changing the focus position. Rotate thedetector for correct alignment. The thumb wheel adjustments may be used to precisely
position the detector - one eighth of a turn of the thumb wheel changes the detector position
by approximately 1/10th of a millimeter.

6.

After each adjustment, ensure the array detector mounting flange is in contact with the
thumb wheel and the two (2) push screws. Tighten the #10-32 set screw on the top of thefront plate first, and then tighten the one on the side to secure the detector.

7.

Best spectral resolution is obtained when the array detector is aligned to the SpectraPro-300i.
The light source can be removed if desired, and replaced by fiber optics or other light sources.

8.

If fibers or other imaging optics are used to bring light into the SpectraPro-300i, they may
require adjustment along the optical axis to achieve best vertical image quality.
19Section IV-E:

Converting the SpectraPro-300i from Monochromator toSpectrograph, or Spectrograph to Monochromator

Monochromator to Spectrograph: This procedure requires that you have the monochromator
version, Model SP-305, plus the array detector mounting flange.
1.

Loosen the two (2) set screws.

2.

Remove the four (4) 8-32 socket head cap screws (SHCS) which secure the exit slit to theSpectraPro-300i housing. Details of the slit assemblies can be found in the drawing locatedin the Appendices Section.

3.

Gently slide the slit assembly out of the SpectraPro-300i housing and store in a clean, dry
area. The exit slit assemblies are attached to a sliding tube which is removed along with theslit body.

4.

Slide the array detector mounting flange into the SpectraPro-300i housing so that it rests
against the housing. It may be necessary to turn the focus-stop thumb wheel counterclockwise so that it does not interfere with the array detector mounting flange.

5.

The SpectraPro-300i has now been converted from monochromator to spectrograph.

6.

Refer to Sections III-E “Mounting Focal Plane Detectors...”, and IV-D “Focus and Aligning
Array Detectors” for actual mounting, alignment, and focus of array detectors.

Spectrograph to Monochromator : This procedure requires that you have the spectrographversion, Model SP-306, plus the Model SP-716-2 exit slit assembly.
1.

Loosen the two (2) set screws and gently slide the array detector mounting flange outof the SpectraPro-300i housing.

2.

Remove the array detector if attached, then store the array detector mounting flange ina clean, dry place.

3.

Locate the Model SP-716-2 exit slit assembly, then gently slide it into the SpectraPro-300i
housing until it rests against the housing. Exit slit assemblies are attached to a sliding
tube to fit the SpectraPro-300i housing.

4.

Using four (4) 8-32 socket head cap screws (SHCS), secure the slit assembly against
the SpectraPro-300i housing. There are four (4) tapped holes in the SpectraPro-300i
housing to facilitate mounting the exit slit.

Note: The slit aperture is slightly offset in the slit assembly. It should be oriented so that theaperture is on the upper side when properly mounted to the SpectraPro-300i. On thebilateral slits, the micrometer points upward. On the fixed slit assemblies you should be
able to read the slit width marking (it will be upright). Please refer to the drawing in the
appendices section of this manual for correct orientation if necessary.
5.

The SpectraPro-300i has now been converted from spectrograph to monochromator .
