- Diameter: 0.6299 inch
- Materials: Polystyrene
Description: Meniscus lenses have one convex and one concave surface. They are used to change the focal length of another lens.
Description: The shape factor of a meniscus lens is chosen to minimize third-order spherical aberration. A meniscus lens would be appropriate for fast systems (f/5 or faster), where the spherical aberration introduced can be much greater than the diffraction effects. In this case, the shape of the lens should
Supplier: II-VI INFRARED
Description: distance). In addition to the standard focal lengths listed here, II-VI maintains an extensive inventory of test plates and tooling. This enables fabrication of many other focal lengths without additional tooling charges. Besides the plano-convex, meniscus, and aspheric lens shapes offered

Supplier: Knight Optical Ltd.
Description: Meniscus lens - Laser Type. 16mmf.lx6.3mdia These meniscus lenses have one concave and one convex surface. In this lens type the two curvatures are chosen to minimise the spherical aberration at one laser wavelength, hence they can be useful to control a laser beam of the appropriate wavelength
- Lens Type: Meniscus
- Focal Length: 0.6299 inch
- Diameter / Length: 0.2480 inch
- Materials: SF11 Glass
Description: A cylindrical lens with Meniscus volume can turn a transmitted plane wave into a cylincrical wave, or turn an original cylindrical wave into a plane wave or spherical wave, such a kind of lens can correct ocular astigmation.
