Sampling Optics: 74-UV-90 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-UV-90 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. Simply screw the reflector on to the end of any SMA-termination to
collect, shape, and focus light to 90°.
