Product Family Description

Positive Focal Length
Micro PCX Lenses for Collecting and Focusing Light
Various Coatings Available: Uncoated, MgF2, and NIR I

Plano-Convex (PCX) Lenses have a positive focal length, making them ideal for collecting and focusing light in imaging applications. They are also useful in a variety of applications involving emitters, detectors, lasers, and fiber optics. These micro PCX lenses are offered with a Telecom-NIR coating optimized for common telecom wavelengths.

These lenses are also available Uncoated, MgF₂ coated and NIR-I coated. Detailed specifications for these coatings can be found in our Anti-Reflection coating primer
