Optical windows general information

  Optical windows usage

Principal usage of optical windows are :

– Protection of optical devices (minimizing optical deformation of optical signal)
– Support for masks, markings and filtering
– Supports for opto-electric components

  Optical windows types

SINOPTIX can provide almost all kind of optical windows :

– Flat of with angle (wedges)
– Round windows, square windows, ellipse windows, ring windows & specific shapes
– Bended windows (float)
– Plastic injection optical windows
