Mechanical Setup
The Thorlabs BC1M2 Extension set for M
2
measurements is not a compact
instrument but consists of separate components which are built together. In addition,
means for beam alignment and focusing need to be ordered separately.
The following sketch gives an example of a M
2
measurement setup.

Mounting the translation stage on a table
It is highly recommended to mount the translation stage onto a table to ensure a fixed
position and repeatable measurements.
Use the base plates delivered with the BC1M2 Extension Set to mount the stage
onto an optical table.
Mounting the BC106 Beam Profiler to the translation stage
First mount the Beam Profiler onto the adapter plate by using the appropriate M6x10
screw delivered with the BC1M2 Extension Set. Therefore put the BC106 Beam
Profiler into the designated bracket and push it slightly against the stop at the front.
This guarantees orthogonal to the moving direction of the translation stage
adjustment of the camera sensor. Then fix the screw.
