Meniscus lenses allow minimal spherical aberrations when a parallel beam enters the convex surface. This results in a minimum focal spot size for the incoming collimated light source. All plano convex and meniscus lenses shown have positive focal lengths. Negative focal lengths are available upon request.

| 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. |
