Optical Window to Measure

Princeton Scientific Corporation offers plane parallel optical components made of crystalline materials with highest precision. Our expertise and years of experience in the field of crystal technology allows us to manufacture various shapes and dimensions according to your specification or drawing.


  • Round and square shapes, different thicknesses
  • Surface quality according to ISO 10110 or MIL specification
  • Flatness up to lambda/10

Prisms - Precise Angles

Prisms belong to the most sophisticated optical components. Depending on their application, they differ in shape, arrangement of the polished surfaces or in the selection of the transmitting material. We offer polished prisms of different crystalline materials upon request.

Lenses - Optics for Beam Shaping

Lenses are essential for optical systems. PSC offers polished lenses in spherical geometry on request made of various crystalline materials. We supply individual components or assembled as part of optical modules.

Mirrors and Mirror Substrates - Precisely Deflected

PSC offers fine polished plane mirror substrates for laser application in small and large quantities according to your individual requirements.


  • Geometries according to customer specification
  • Flatness up to lambda/10
