Double Concave Lens,Spherical Bi-concave Lens We're the optical lens processing company. Spec: customized drawing Use: all
Concave Mirror, Biconcave Mirror Lens, Plano Concave Mirror Lenses
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.
Specifiction of our Spherical lens as follow:
Focal length tolerance
A: AR Coating 350nm-650nm
B: AR Coating 650nm-1050nm
C: AR Coating 1050nm-1580nm
