Plano-convex lens element PCX

CaF2UV

* Diameter (metric): 12,5 - 25,0 mm * Diameter (imperial): 0.5 - 1 inch * Diameters up to 4 inch available on request * Focal length from 25 mm to 1000 mm Plano-Convex (PCX) Lenses have a positive focal length (from 25 mm to 10.000 mm) and have an excellent shape for minimizing spherical aberration for infinite conjugate applications. These simplest form lenses have flat surface on one side and spherical surface on the other. They are widely used in telescopes, microscopes, collimators, optical transceivers, magnifiers, condenser systems and eyepieces, where light collimation or focusing is needed. Lenses made of Calcium Fluoride (CaF2), which is used for its high transmission from 350 nm to 7 μm and low refractive index. PCX lenses made of UV FS (UV grade Fused Silica) and BK7 optical glass are also available. Lenses can be supplied with a coating of your choice.
