Visible Meniscus Lenses

Meniscus Cylindrical Lens
from BRD Optical Co., Ltd.

Meniscus Cylindrical 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... [See More]

Cylindrical Lens
from Intrinsic Crystal Technology Co., Ltd. (ICC)

A cylindrical lens is typically used to focus, condense or expand incoming light. A cylindrical lens has one cylindrical surface, causing light to be focused in a single dimension or axis. It can also be used to expand the output of a laser diode into a symmetrical beam. ICC supply various kinds... [See More]

Steinheil Triplets -- L-AST001
from Ross Optical Industries

The Steinheil triplets are made of a low index crown element cemented in between two identical meniscus flint elements. Specially designed for 1:1 conjugation, they perform well for conjugate ratios up to 5. These lenses make good relay optics for both on- and off-axis application and are often used... [See More]
