Fiberoptic Systems, Inc. is a leading company in the field of fiber optic applications. We manufacture a vast array of OEM products used to measure chemical compositions, perform medical procedures, measure color/physical properties, and quantify radiance in the ultra-violet(UV), visible, and infrared (IR) regions of the spectrum.

The flexibility afforded by fiber optics enables an unlimited number of solutions in semiconductor, entertainment, spectroscopy, military, microscopy, medical, and machine vision markets.

Since 1982 we have worked with borosilicate, fused silica (quartz), fluoride, silver halide, chalcogenide, and plastic optical fibers. The bulk of the fibers we use in our assemblies are manufactured in-house.

From prototype to production, UV to IR, cryogenic to high temperature, short to long, we will help design a solution to fit your budgetary, timing, and quality requirements.
