Introducing Shamrock 750
The Shamrock 750 offers the highest resolution of the
Shamrock family, but is also well suited for applications
requiring multi-track capabilities. This rugged platform
features a comprehensive range of light coupling
accessories and gratings, and combines ideallywith Andor’s market leading CCD, Electron Multiplying
CCDs, InGaAs and Intensified CCDs.

3

1 Chassis configurationa) Select combination of input and output ports (see page 3 for available options).
b) Select type of optics coating required (aluminium + MgF2 is standard, protected silver coated optics available on 		
request for NIR detection).
c) Select purge port option (for improved detection down to 180 nm), and shutter for background acquisition anddetectors protection.

2 Resolution & band-passa) Select the appropriate Shamrock spectrograph platform, giving due consideration to bandpass and spectral range
requirement.
b) Select gratings and detector to fulfil resolution requirements.
c) Select gratings for suitable wavelength coverage.

3 Input light coupling interface
Refer to accessory tree for available configurations (direct coupling, fibre coupling or third party hardware connectivity).

2nd exit port configuration

Refer to accessory tree for available configurations, including camera flanges.

5 Software interface
Select either state-of-the-art Solis software or Software Development Kit (SDK) option – please refer to appropriate

Czerny-Turner spectrographs are designed to provide the best optical performance for a range of grating angles asreflected on the green parts of the graph above. Outside this range, the spectral lines may exhibit a degree of opticalaberration (such as coma), which will become more prominent at the steeper angles. These configurations are reflected by
the orange to red scales on the graph. In these regions, consideration should be given to higher spectrograph focal length
models with lower groove density gratings to achieve the desired resolution.

Where aberration is a concern for a particular experimental set-up, the table above shows resolution and band-passperformance for a variety of alternative configurations. This should be used in conjunction with the graph above to assist
in selecting the most appropriate Kymera or Shamrock spectrograph platform to meet resolution and band-pass needs,
whilst minimising the risk of potential aberration.

Step 2b - Choosing The Right Grating vs Resolution and Band-pass
The Shamrock 750 features an innovative triple grating turret, designed to offer flexibility and control over yourchoice and interchange of gratings. The triple grating turret can be easily and speedily removed, and replacedby an alternative turret with new gratings. The intelligent design of the 750 means that only a simple offset
adjustment is required once the new turret and gratings are added. The 750 is shipped with the grating turretalready in place, ensuring your system is ready for use straight out of the box. Additional grating turrets areavailable with up to three pre-installed gratings (see below for details). If the grating you require is not on the list, pleasecontact Andor for further details. Additional grating turrets (part number SR-ASM-0085) can also be supplied on request.

The Shamrock 750 requires at least one of the following software options:
1 - Solis Spectroscopy A 32-bit and fully 64-bit enabled application for Windows (8.1 and 10) offering rich functionality fordata acquisition and processing, as well as Andor cameras, spectrograph and motorized accessories simultaneous control.
AndorBasic provides macro language control of data acquisition, processing, display and export.

Multi-track Capabilities
Imaging, or multi-track, refers to the ability - in the context
of a spectrograph - to isolate a series of individual,
vertically-stacked spectrum channels with minimum
cross-talk.
Czerny-Turner spectrographs are based on off-axis imaging,which introduces distortion at the output focal plane due
to aberrations. The introduction of toroidal optics to correct
for these aberrations is common for instrument with shorter
focal length, i.e. below 600 mm. These ‘imaging’ correction
optics effectively pull together the focal plane of best
spectral and best spatial resolutions, known respectively
as the tangential and sagittal planes.

Figure 1. Images produced at the exit of the Shamrock 750 with light from a Mercury
source (577 and 579 nm lines) and 100 µm core fibre-optic.
a. Shows elongation of spectral lines when using the standard Shamrock 750 sphericalmirrors - well suited to high-resolution, single spectrum acquisition.
b. Shows demagnification of spectral lines with optional correction optics SR-ASZ-0033- this allows stacking of multiple spectral channels with minimum vertical cross-talk andwith no impact on spectral resolution.

However, greater focal length spectrographs, such as
Shamrock 750, are principally used for very high spectral
resolution from a single spectrum. These instruments are
therefore based on classical spherical mirrors and lead tosome elongation of the signal in the vertical/imaging axis
as shown on Figure 1a, hence limiting stacking of multiple
spectral channels.
Andor’s optional accessory, SR-ASZ-0033, allows
correction of the optical line elongation as shown on Figure
1b, whilst maintaining the spectral resolution performanceof the system. Moreover, this accessory introduces ademagnification of around 0.75 therefore increasing thepossible density of tracks in the vertical/imaging direction.
Figure 2 illustrates this optical improvement through theuse of a broadband source, showing the well-definednarrow channels with minimum cross-talk.
Please contact your local sales representative for further
information on high-density, multi-channel fibre-optics.

Footnotes: Specifications are subject to change without notice
1. In the case of a multiple grating turret order, please specify desired grating configuration for each turret.
2. SR-SHT-9002 calls for 1x shutter. For dual input port options (C, D1 & D2) it is recommended to order a shutter foreach port. Shutter operation only requires BNC to SMB cable from USB cameras.
3. Typical values quoted with 27.6 mm wide CCD, e.g. Newton DU940.
4. Typical values quoted with 10 μm slit and 13.5 μm pixel CCD, e.g. Newton DU940.
5. Typical values quoted at 500 nm centre wavelength.
6. Typical values quoted at 300 nm centre wavelength.
7. Typical values quoted at maximum efficiency wavelength or blaze wavelength unless otherwise stated..
8. Wavelength within the recommended operating spectral region.
9. Indicative values; the working range of these gratings is principally in the region where optical aberrations mayalter the system resolution performance quoted.
10. Values shown are representative of a triple grating system, where resolution has been Optimized to give the best
performance for the three gratings and across the full recommended wavelength range. Useful signal is assumed
to be imaged on the entire height of a 6.9 mm sensor (i.e. Newton DU940) and fully vertically binned.
11. Please refer to F/# matcher specification sheet for magnification considerations.
12. Please refer to the local sales representative or website for further information on available options andcomplimentary accessories.
13. Slit widths range from 10 μm to 2.5 mm.
14. For B2 and D2 configurations only - to be ordered separately.
15. Please specify relevant port at time of order.
16. Provided as standard.
17. Recommended for use with fibre-optics and C-mount accessories.
18. Please refer to Shamrock 750 multi-track, imaging technical section for further information.
19. Measured with a 633 nm laser and a 1200 l/mm grating for Full Vertical Binning (FVB) on a 6.9 mm high sensor,
and a 1 mm strip vertically centred on the optical axis.
20. Average measurements using > 30 calibration lines, covering the recommended grating angle operating range
with a 1200 l/mm grating.
21. The standard deviation of 20 measurements of a peak’s centre-of-mass position: between each measurement
the drive is moved 10x including both wavelength and grating changes to reflect typical use.
22. Side accuracy measured using a 27.6 mm wide sensor, reflecting the dispersion calibration and step-and-glueaccuracy.
23. Only Andor CCD platforms (Newton, iDus, iKon) can be controlled in conjunction with Kymera and Shamrock 		
spectrographs in EPICS software.
