Equipment needed:
• Pedestals
Note: The module mounting brackets have M6 holes, hence
pedestals with M6 tapered holes are recommended.
3. Installation
3.1 Module preparation
The irst step is to determine the working beam height H, and
choose and install the appropriate pedestals to elevate the
CANUNDA-PULSE module at the correct working height.
The module input is 35 mm above the bottom surface of the
module mounting brackets. The beam height His then related
to pedestals height Hpby:
H=Hp+35 mm
Example: With 50 mm pedestals, the beam height His 85 mm
Turn on your laser source. For the whole installation procedure,
a laser power of 10 mW is enough.
As depicted in the previous picture and using the IR Card to
check the position of the laser beam, manipulate the alignment
mirrors to make sure that the beam is:
• Parallel to a line of breadboard holes
• With constant height H as determined in section 3.1
Locate the beam waist. The input laser beam must have a
500 µm waist located at a distance ≥150 mm from the last
mirror. If the laser beam is smaller or larger, use a beam
expander/reducer or a telescope to adapt the input beam
dimensions.
Equipment needed:
• 2x Alignment mirrors (with kinematic mount)
• IR Card
• Graduated ruler
3.2 Beam preparation
Position and secure the two alignment mirrors to the
breadboard as depicted in the picture below (the more
separation between the mirrors, the better).
