ZINC SELENIDE(ZnSe) PLANO-CONCAVE LENSES Download PDF document

These plano-concave lenses are manufactured CVD grown Zinc Selenide. They have a low absorption in the infra-red. Negative focusing Zinc Selenide lenses are perfect for thermal imaging and Carbon Dioxide laser focusing applications.

We supply uncoated but a range of anti-reflection coatings can be applied as well for CO2 laser applications.

NOTES!  
ZnSe reacts readily with acidic substances, generating toxic selenium oxide gas. Never clean with acidic washing solutions.
Note that 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.
