Optica Biconcave Lens
Description
Bi-Concave Lenses are symmetrical with equal radii on both sides. The biconcave 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.

Frequently Asked Questions
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 Bi-Concave Lenses are laser beam expanders, optical character readers, viewers, and projection systems.
Plano Concave (PCV) Lenses have one flat and one inward curved surface, while Bi-Concave Lenses are symmetrical with equal radii on both sides.
Bi-Concave Lenses are commonly used in laser optics, OEM, microscopy, spectrometry, industrial, commercial, and scientific applications.
Bi-Concave Lenses can reduce spherical aberration, coma, and distortion at negative-infinite or near-infinite conjugate ratios. They also diverge collimated incident light and form only virtual images which are seen through the lens.
