Description

Details

Being designed as precision windows/substrates to distinguish by supreme surface polishing quality as well as surface flatness and parallelism makes the windows indispensable article for most precision demanding applications. Special polishing technique is used to bring surface smoothness and flatness nearly to perfection. This product is an ideal substrate to produce mirrors/polarizers for high power applications since laser induced damage threshold (LIDT) value is closely related to surface polishing quality. Negligible parallelism error (<5arcsec) causes minimum misalignment errors, when component is repeatedly inserted and removed, this particular property makes it first choice item when one needs substrates for plate beamsplitters and thin film polarizers with minimal beam deviation.

Features
  • Superior polishing quality (10/5 Scratch/Dig)
  • Negligible parallelism error (<5 arcsec)
  • Ideal for low scatter demanding applications
  • Same polishing quality applies to both surfaces
  • Minimum misalignment errors when window is repetitively inserted and removed
