2. To replace the optic, heat the epoxy with a heat gun. Using a sharp blade,
gently pry or cut the epoxy away from the optic and mount. Care should be
taken to avoid injury.
3. Clean any residual 2216 epoxy from the mount.
NOTE:
Use gloves when handling optics
4. Inspect the new optic and identify the optical surfaces. Lay the 9774 mount
flat on its back. Place three tack points of 2216 epoxy on the inner lip of the
mount to bond the optic in place approximately 120 degrees apart. Only a very
small amount of epoxy is needed. Place the optic in the 9774 mount with the
HR coating facing up. An arrow on the side of the optic points toward the HR
coating. Avoid getting the epoxy on the optical coatings. Additional epoxy
may be used on the front edges of the optic as seen in the
(page 24) section. Allow 12 hours to cure the epoxy.
5. Re-inspect the optic and clean as needed after the 12 hour cure time.
6. Clean any residual 2216 epoxy from the mount.
7. Install the HM assembly to the bench using the (3) 8-32 x 5/8" screws.
Torque the 8-32 screws to 25 in-lbs.
1. Visually inspect internal laser housing and optical bench for cleanliness using
a high intensity light. Remove all dust particles and debris.
