ZINC SELENIDE (ZnSe) Beamsplitters Download PDF document

Beamsplitters is set at 45° angle of incidence to receive orthogonal beams (being reflected and passed). While the reflectance/ transmittance ratio will be singnificantly different for S- and P- polarisations at 45° angle of incidence.

The polarisation state of the laser must specified when ordering this position.

NOTES!  
ZnSe reacts readily with acidic substances, generating toxic selenium oxide gas. Never clean with acidic washing solutions.
ZnSe is classified as a toxic material by law. Transactions involving ZnSe or products incorporating ZnSe require a certificate of transfer.
Disposal of ZnSe optics as general waste is prohibited. Please notify us if you need to dispose of such products. (Ultiquest Technolgies products only.)
Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
