Meniscus (Material: H-K9L)

Meniscus Lenses are concave-convex lenses that contain both positive and negative meniscus lenses. The Positive meniscus lenses are thicker in the middle than at the edges, allowing light to converge, and are designed to reduce tertiary spherical aberration. When they are used to converge a collimated beam, the convex side should ...

Specifications

Material: H-K9L
Diameter: 12.7 mm
ROC1: 7.5 mm
ROC2: 72.4 mm
Diameter Tolerance: +0/-0.1mm
The Positive Meniscus (Convex-Concave) Lens is an essential optical component designed to optimize performance by minimizing spherical aberration. These lenses are characterized by their unique shape, featuring a convex surface on one side and a concave surface on the other. This design is particularly beneficial when the lens is ...

The Negative Meniscus (Convex-Concave) Lens is an essential component in advanced optical systems, meticulously designed to minimize spherical aberration. This lens features a unique shape with a smaller center thickness, allowing it to effectively increase the focal length and decrease the numerical aperture (NA) when used in ...
