TECHSPEC® PCX Uncoated Lenses

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. Coated versions have optimum light transmission. Available in a wide variety of diameters and focal lengths.

These lenses are available with a variety of anti-reflection coating options including:VIS-NIR, MgF2, VIS 0° and NIR-I. 1-3mm diameter lenses are also available with a Telecom-NIR anti-reflection coating.
