Cylindrical lenses are utilized for astigmatism correction in the eye and rangefinders, inducing astigmatism by elongating a point of light into a line. They find extensive application in barcode scanning, projection optics systems, laser measurement systems, and holography. Ost Photonics offers cylindrical lenses in plano-concave or plano-convex configurations.

Calcium fluoride is often used in spectroscopic windows and lenses due to its high transmission from 250nm to 7μm. Its low absorption and high damage threshold makes it a popular choice for excimer laser optics. Calcium fluoride's low index or refraction allows it to be used without an anti-reflective coating. The Knoop hardness of calcium fluoride is 158.3. Calcium Fluoride (crystran CaF2) windows manufactured from vacuum UV-grade calcium fluoride are commonly found in cryogenically cooled thermal imaging systems.
