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. |
