Positive meniscus lenses is convex-concave lens thicker at the center than at the edges. They are used to minimize spherical aberration. When used in combination with another lens, it’s will shorten the focal length, and increase the NA of system.

CaF2 has transparent range from 170-7800nm. The refractive index is 1.399 at 5000nm. 1. Low absorption coefficient 2. High damage threshold, 3. Low Dispersion (with an Abbe Number of 95) 4. Low fluorescence 5. Excellent water, chemical, and heat resistance
