PAS: Photo Detectors, Vacuum Spatial Filters and Optical Filters
Precision Applied Science is a professional manufacturer and supplier of detectors, optics, and hardware for detecting, measuring, and controlling light from lasers and other sources.
Our rugged high performance PIN photodetectors are useful for the detection of light signals from 190nm to 1700nm.
Optical filters attenuate or diffuse light to reduce intensity to levels required for use or measurement.
Vacuum spatial filters are custom designed for high power laser systems to control beam quality, prevent air breakdown, beam expand, image relay and retard nonlinear self-focusing.
