Sapphire Meniscus Lenses

Spheric Lens
from Foctek Photonics, Inc.

FOCtek provides five kinds of spheric lens forms, or shapes, that determine the imaging Characteristics. of the lenses, they are plano-convex, plano-concave, Double-convex, Double-concave and Meniscus. Plano-convex lens has a positive focal length, which makes it ideal for collecting and focusing... [See More]

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]
