What is a meniscus lens
Meniscus cylinder Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens.
Description Of Meniscus Cylindrical Lens
It is a lens that one surface is the convex shape, another surface is concave with a cylindrical shape, its role is making beam converging or diverging on a plane, and that beam doesnt work for the perpendicular plane(cylindrical axis) with it. A cylindrical lens is used in turning a transmitted plane wave into a cylindrical wave, or turn an original cylindrical wave into a plane wave or spherical wave, such a kind of lens can correct ocular astigmation.

customized quartz glass components has a high transmittance from ultraviolet to near-infrared (185nm-00nm), and has a high transmittance in the deep ultraviolet region, making it widely used in ultraviolet lasers. In addition, compared with ordinary optical glass, fused quartz glass has better uniformity and lower thermal expansion coefficient, making it particularly suitable for applications in the ultraviolet to near-infrared wavelength range, high-power lasers and imaging fields. As a professional fused silica manufacturer, Ecoptik can provide the best fused silica, if you want to know the fused silica price, please feel free to contact us.
