20-10 Scratch / Dig 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]

Meniscus Lenses

Meniscus lenses are designed to minimize spherical aberration producing a minimum focal spot size for incoming collimated light. In addition to the standard focal lengths listed below, II-VI maintains an extensive inventory of test plates and tooling, resulting in no additional tooling charges for... [See More]
