74-90-UV Right Angle Reflector
The 74-90-UV R IGHT A NGLE R EFLECTOR is a 3/8-24 threaded black anodized aluminum assembly for mounting
collimating lenses at right angles, and is useful for applications involving limited space and inconvenient optical
fiber routing.
Application Tips
" The 74-90-UV Right Angle Reflector has a plane mirror located under its cap that reflects light from the
collimating lens to 90°. This mirror is coated with a UV-enhanced aluminum substrate that is >90% reflective
from 200-1100 nm.
" The 74-90-UV has two 3/8-24 threaded ports -- at top and bottom -- that accommodate collimating lenses. The
top port has a 3/8" x 1" threaded nipple that can be removed for connecting to a male adapter.
" Using the 74-90-UV is easy. Screw in a collimating lens into a port and attach a fiber to the collimating lens.
For directions on adjusting the focus of a collimating lens, see Appendix B .
