These plano-convex lenses are manufactured CVD grown Zinc Selenide. They have a low absorption in the infra-red. Positive 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. |
