Optical CaF2 Calcium Fluoride Lens BaF2 MgF2 Magnesium Fluoride BK7 Fused silica Glass Meniscus Lens
Compare
Meniscus Lenses are concave-convex lenses that contain both positive and negative meniscus lenses. The Positive meniscus lenses are thicker in the middle than at the edges, allowing light to converge, and are designed to reduce tertiary spherical aberration. When they are used to converge a collimated beam, the convex side should ...

Positive Meniscus Convex-­Concave Lens
Compare
Positive meniscus (convex-concave) lenses, with center thickness bigger, are designed to minimize spherical aberration. When used in combination with another lens, a positive meniscus lens will shorten the focal length and increase the numerical aperture (NA) of the system without introducing significant spherical aberration. When ...

Negative  Meniscus Convex-­Concave Lens
Compare
Negative meniscus (convex-concave) lenses, with center thickness smaller, are designed to minimize spherical aberration in optical systems. When used in combination with another lens, a negative meniscus lens will increase the focal length and decrease the numerical aperture (NA) of the system. When used to diverge light, as shown in ...
