Portable Optical Tweezers Kit Chapter 6: Setup and Adjustment
Rev B, July 8, 2019 Page 27
Note: We recommend using a grounding bracelet when
handling the laser diode to prevent damage.
Take the L658P040 laser diode from its package and place
it in the silver retention ring of the LTN330-A, see the image
to the right.
Remove the retaining ring from the LTN330-A housing.
Then, insert the diode with the silver retention ring into the
LTN330-A.
Fix the assembly in the LTN330-A using the black retaining
ring (the retaining ring can be tightened using a thin
screwdriver). Make sure to use the thick retaining ring and
not the one you unscrewed in the previous step. Also,
ensure that the laser
diode’s legs fit through the center hole
so they are not damaged, see image to the right.
In the next step,
insert the laser diode’s legs into the socket
of the SR9A-DB9. Please be careful in this step to avoid
damage to the diode.
When the diode’s legs are in the socket, the cover can be screwed onto the LTN330-A.
Make sure to screw on the part labeled “SR9A-DB9” instead of rotating the part with the
printed circuit board!
Finally, secure the
assembly in the AD15F by
engaging the two nylon-
tipped
setscrews, see
image to the right.
