Eksma optics Precision round window

The windows are designed to be used in precision optical systems.

The optical transmission is high with little distortion of transmitted signal.

λ/10 transmitted wavefront distorsion is usually preferred but λ/4 is offered as an option when this is not an issue.

Diameter up to 250 mm is available on request.

  • manufactured from high quality UV FS and BK7
  • precision polished on both surfaces and held parallel up to 3 arcsec
