Device description

4.1

Device type overview

There are two types of the BeamMonitor BM+.
BeamMonitor BM+ 60

Fig. 4.1:

4.2

BeamMonitor BM+ 100S

Device types BM+ 60 and BM+ 100S

Functional description

The BeamMonitor BM+ is an opto-mechanically scanning measuring system that scans the laser beam witha special measuring tip. This is equipped with a small pinhole or reflecting mirror that collects a small sectionof the laser beam. Another reflecting mirror guides this portion of the laser light to a detector selected andconfigured depending on the used wavelength.
By moving the rotary disk forth a power density distribution is created. The high orbital velocity of the rotating
measuring tip facilitates analysis of high power densities. A very high signal-to-noise ratio is achieved thanks
to the dynamics of the analog-digital converter used. Very low intensities are shown with equal precision next
to the high peak intensities.

4.3

Measuring principle

Using the new LaserDiagnosticsSoftware LDS you can set up the BM+ to automatically repeat measurements in a predefined interval. Accumulate unlimited measurements and check how the beam profile or location changes over a long time. For the consideration of shorter time intervals the established Linescan can beused up to a frequency of 25 Hz.
With a newly developed algorithm, the automatic recognition and analysis of rectangular beams becomesquite straightforward. Besides the lateral length, many unique parameters like the azimuth angle, flank steepness, flatness and uniformity are precisely calculated.

Explanation of the product safety labels

4.5.1

Warning of hand injuries

A potential hazard area for hand injuries and device damage is marked with a symbol on the device.
The measuring tip of the BeamMonitor BM+ rotates at high speed during the measuring operation. Even after the measurement or switching off the device, the measuring tip will continue to rotate for a certain amountof time. To avoid hand injury, do not reach into the aperture of the device.
If the rotating measuring tip hits an obstacle, the measuring tip is de-adjusted. In this case, the device must
be sent in for service. Therefore, no objects may get into the aperture.

Align the device

For the BeamMonitor BM+, a perpendicular beam incidence with respect to the x-y plane must be ensured.
The laser beam should hit the inlet aperture in the center.

DANGER
Serious eye or skin injury due to laser radiation
If the ratio of the laser beam diameter to the inlet aperture is too large, increased scattered or directed reflection of the laser beam (laser class 4) will occur during measuring operation. The housing of the BeamMonitor BM+ can heat up.
X The 86 % laser beam diameter must not exceed 0.7 times the inlet aperture.
X Especially in case of laser with high beam quality, the laser beam diameter must not exceed 0.6
times the inlet aperture. Otherwise, a falsification of the measuring results due to the cutting off ofborder fields is to be expected.
This can lead to measurement errors, especially when determining the radius using the second moment method.

7.2.4

Mount the device

DANGER
Serious eye or skin injury due to laser radiation
If the device is moved from its calibrated position, increased scattered or directed reflection of thelaser beam occurs during measuring operation (laser class 4).
X Mount the device in a way that it cannot be moved by an unintentional knock or cables being pulled
accidentally.

NOTICE
Damage / Destruction of the device
Too long fastening screws can damage internal components in the device.
X The fastening screws must not be screwed in more than 10 mm into the housing.
There are four threaded holes M6 in the mounting surface of the housing for assembly on a support bracket
provided by the customer (see Fig. 7.2 on page 16 and Fig. 7.3 on page 17).
Please use at least four screws M6 to fasten the device. The total length of the screws depends on the dimensions of the customer’s support bracket.

Single planes

In Single planes measuring mode, single planes are measured at selected z-positions. Measurement window size and the gain can be set automatically or determined freely. You can also have the software search
the laser beam automatically in the entire measurement range.
To measure a manual caustic (see chapter 9.4.6 „Manual caustic measure“ on page 39), several planes
can be measured — either individually or by means of a series measurement. Therefor, an increment along
the z-axis can be configured. Since the BeamMonitor BM+ does not have a z-axis, the laser or the device
must be moved according to the entered value. With this procedure, a manual caustic can be measured.

The power density is too low.

Increase the laser power (step by step).
The absolute power density should typically be a few
kW/cm² (max. 10 kW/cm²) to achieve a significant
measurement signal.

For small beam diameters (e.g.
r<6 mm) and maximum measuring window, the resolution is
too low.

Increase the resolution in the dialog window Device
control > Single plane > Advanced in the Pixel inx/y section to something like 1 024 x 1 024 pixels.

The signal enhancement is too
low.
