Alpha Optik produce customized linear single-mode or multi-mode fiber arrays with angle polished end silicon v-grooves.
Polished Construction Features: silicon v-grooves, durable multi-layer dielectric coatings,low absorption characteristics,environmentally-stable,robust and easy-to-clean.
Please specify: Number of fibers, pitch, wave length, type of fiber, and polishing angle,ends are AR Coated. Multi-layer,all dielectric AR coatings are applied for peak performance at specified wave lengths in 1350 to 1650 nm range.
Applications: Optical switches, attenuators, optical Isolators,R&D, etc.
We produce actively aligned, rugged, lensed fibers with Durable multi-layer.

AR Coated Lensed Fibers We produce actively-aligned,rugged, lensed fibers with Durable, multi-layer Dielectric coatings on the spherical lens. Overall dimensions of Zr-sleeve is -10.5 mm long and OD+3.2 mm. Standard fiber length is 1 meter. Construction Features: Durable multi-layer dielectric coatings, low absorption characteristics, environmentally-stable, robust and easy-to-clean. Each piece is optically actively aligned.
