Ocean Optics Releases Fiber Optic
Collimating Lens Accessories

DUNEDIN, FL -- Three new  fiber optic collimating lens accessories from Ocean Optics, Inc. are designed to enhance the proficiency and convenience of the optical interface part of the spectrometer system.  According to the company, these devices can  make it easier to mount lenses in various positions and to integrate lenses  into otherwise awkward optical setups.   The 74-90-UV Right Angle Reflector is a 3/8-24 threaded black anodized aluminum assembly for mounting lenses at right angles; it is designed for applications involving limited space and inconvenient optical fiber routing. It has a mirror located under its cap that reflects light from the collimating lens to 90 degrees and is coated with an 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 also has a 3/8" x 1" threaded nipple that can be removed for connecting to a male adapter.  The 74-OPM Optical Post Mount is a 3/8-24 threaded black aluminum assembly for mounting collimating lenses on laboratory tables, rail carriers,  and other bench plates. This assembly has a bore for mounting the holder onto an optical post; it is threaded in the center to hold a collimating lens securely in place in a variety of positions.   The 74-ACH Adjustable Collimating Lens Holder is an assembly for mounting opposing lenses at multiple positions; it is also designed for transmission measurements of large or thick samples not easily accommodated by other sampling optics.   PTB Home
