74-90-UV right angle collimator


SKU: N/A Category:


Ocean Optics 74-90-UVs are 3/8-24 threaded black anodized aluminum assemblies for mounting lenses at 90°, for applications involving limited space and inconvenient optical fiber routing. Versions are available for coupling to a pair of optical fibers or to an optical fiber on one end and a cosine corrector on the other.

Each 74-90-UV right angle collimating lens mount has a mirror under its cap that reflects light from the collimating lens to 90°. The mirror is coated with an aluminum substrate that is >80% reflective from 200-1000 nm. A pair of 3/8-24 threaded ports accommodate collimating lenses (not included). The top port has a 3/8″ x 1″ threaded nipple that can be removed for a connecting to a male adapter.
