Spherical Biconcave Lenses, Optical Concave Mirror
Optical lense is a precision optical component for camera, video camera, telescope, film projector. duplicator,
microscope and other observation instruments. The applications of optical lenses. It is apply for stage light,
vidicon. camera lens, telescope, fingerprint identify instrument, microscope, digital camera, and so on! The
ordinary optical lense is suitable for magnifier, stage lighting, and as well as other instrument!
Bi concave glass lenses are manufactured with both surfaces concave. These lenses have negative focal lengths.
These lenses diverge collimated incident light and form virtual images, which are seen through the lens. They are
often used to expand light or increase focal lengths in existing systems. They are used in laser beam expanders,
optical character readers, viewers, and projection systems. Antireflection coatings can be ordered as an option.
