Precision Thin Round Windows

  • manufactured from high quality FS or UV grade Fused Silica
  • precision polished on both surfaces and held parallel up to 30 arcsec
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.
Windows can be anti-reflection coated, for required coating please refer to the COATINGS section.
