Windows & Wedges


SIO produces windows for a wide range of applications including general commercial as well as medical, avionics, military and space. We can produce our windows from commercial grade characteristics to precision parallelism within 1 second of arc and flatness to 1/20th of a wave.

SIO manufactures windows from materials such as:

  • Silicon
  • Germanium
  • Optical Glass


Wedges are optical elements having two plano, angled surfaces. Wedges are used for beam steering, beam displacement or correction. SIO also produces achromatically corrected wedges.

The deviation can be produced to customer requirements.
