700 Series Temperature Controlled Mounts
700C: Installing the Collimating Lens Assembly (700-42)
The 700C temperature controlled mount is designed for customers who want to have the option of
collimating their divergent light sources (laser diodes). The 700-42 collimating lens assembly, which is
purchased separately, is pre-installed into a "lens housing" assembly shown in Fig.1.
Unscrew the lens cartridge from the 700C mount prior to installation of the 700-42. First, the black
protective lens cover must be removed from the front of the 700C. Gently unscrew the now visible lens
cartridge, see Fig. 2.

The 700-42 is then installed in the back of the lens cartridge that is shown in Fig. 3. The 700-42 is held in
the lens cartridge via a set screw that is located on the lens cartridge.
Reassemble the mount and the collimation can be adjusted by turning the lens cartridge while
observing/measuring the collimation.
