Description

Negative Meniscus Lens, UV Fused Silica, Minimize Spherical Aberration Lens

Overview:
Negative meniscus (convex-concave) lens is 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 without introducing significant spherical aberration. When used to diverge light, the convex surface should face the beam to minimize spherical aberration. Star Optic provides positive meniscus lenses in a variety of substrates and anti-reflection coating options.

Coating Options Of UV Fused Silica Negative Meniscus Lens:

Star Optic's above standard negative meniscus lenses are uncoated. In order to reduce the amount of light reflected from each surface of the lens, antireflection coatings including singer layer MgF2, multi-layer AR coating, Broadband multi-layer AR coating and Dual wavelength AR coating are also available.

Single Layer MgF2 Coating	Multi-layer Anti-Reflective Coating

Boradband Anti-Reflective Coating	Dual Wavelength Anti-Reflective Coating

Mounting Options For Negative Meniscus Lens:

Star Optic's above standard negative meniscus lenses are not mounted. However, we can provide fixed mount and adjustable mount for our lenses.
