Description
- Have negative focal lengths diverge collimated incident light
- Form only virtual images which are seen through the lens
- Minimize spherical aberration, coma and distortion at unit conjugate ratio
These 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 utilising biconcave lenses are laser beam expanders, optical character readers, viewers and projection systems.
A variety of anti-reflection coatings is available for these lenses. For appropriate coating please refer to the Coatings section of the Optical Components catalog. We can supply custom cutting, edging, coating or complete fabrication if required.
