Ge Meniscus

YuTai Optics Meniscus Lens
Yutai Optics
One side of meniscus lens is convex, another side is concave. It can be a convergent lens or a divergent lens, which is decided together by refractive index, curvature and radius.

Specifications

Material: BK7, FS, CaF2, Ge
Diameter: 300 mm
ROC1: -- mm
ROC2: -- mm
Data Sheet
West Coast Tech Limited Negative Meniscus Lens
West Coast Tech
The best lens from where one conjugates is relatively for from the lens or where both conjugates are the same size of the lens.

Data Sheet
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 ...

Data Sheet
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 ...

Data Sheet
The Positive Meniscus Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. Meniscus lenses as two curves of the lens lies on the same direction.
