Zinc selenide Plano-Convex (PCX) lenses

Edmund Optics has doubled its offering of stock zinc selenide Plano-Convex (PCX) lenses. These lenses are an ideal choice for high power laser applications, thermal imaging, and medical systems.

The lenses are available individually, in diameters of 12.7, 25.4 and 50.8mm with a variety of focal lengths in both uncoated and 8-12μm AR coated models. The anti-reflection coating is optimised to have less than 0.5 per cent reflection from 7.5-13.5µm. A lens kit containing all nine uncoated 25.4mm diameter zinc selenide PCX lenses is also offered.

The lenses offer a usable transmission range of 600nm to 16μm with low dispersion. Lenses with the 8-12µm anti-reflection coating are ideal for thermal imaging applications. Zinc selenide is a chemically vapour deposited material that requires careful handling during mounting and cleaning, as it has a Knoop Hardness of 120. It is not recommended for use in harsh environments or for handling with tweezers or other tools.
