Positive Meniscus Lens, N-BK7, Low Spherical Aberration Lens

Overview:

Positive meniscus (convex-concave) lenses 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 used to focus a collimated beam, the convex side of the lens should face the source to minimize spherical aberration. Star Optic provides positive meniscus lenses in a variety of substrates and anti-reflection coating options.
