Frequently Asked Questions
A Plano-Concave Lens is a lens with one flat and one inward curved surface, which has a negative focal length and is used for image reduction or to spread light.
Plano-Concave Lenses have negative focal lengths, diverge collimated incident light, form only virtual images which are seen through the lens, reduce spherical aberration, coma, and distortion at negative-infinite or near-infinite conjugate ratios, and have the concave surface facing the longest conjugate distance.
Plano-Concave Lenses are used in laser optics, OEM, microscopy, spectrometry, industrial, commercial, and scientific applications.
A Plano-Concave Lens has one flat and one inward curved surface, while a Bi-Concave Lens is symmetrical with equal radii on both sides. Bi-Concave Lenses are often used to expand light beams or to increase focal lengths in optical systems, and are normally used in combination with other lenses.
Among the many devices utilizing biconcave lenses are laser beam expanders, optical character readers, viewers, and projection systems.
