Attention! You can customise this product to your needs.
Being designed as precision windows/substrates to distinguish by supreme surface polishing quality as well as surface flatness and parallelism, which makes the windows indispensable article for most precision demanding applications. Special polishing technique is used to drive surface smoothness and flatness nearly to perfection. This product is 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 beamsplitters and thin film polarizers with minimal beam deviation.
varna Superior polishing quality (10/5 Scratch/Dig)
varna Negligible parallelism error (<5arcsec)
varna Ideal for low scatter demanding applications
varna Same polishing quality applies to both surfaces
varna Minimum misalignment errors when window is repetitively inserted and removed
