描述
BICONCAVE LENS
A biconcave lens is capable of diverging parallel incident light beams outward, with a negative focal length. It consists of two concave surfaces with equal curvature and is commonly used for beam expansion, collimation, projection, and enlarging the focal length of optical systems. Double concave lenses have a negative focal length and are suitable for diverging and converging light beams, also known as diverging lenses or negative spherical lenses. A biconcave lens can diverge a collimated beam onto a virtual focal point, typically used in Galilean beam expanders.
The wavelength range is 350-2200nm
With precise diameter and centripetal tolerances, OEM integration can be easily achieved
Provide various diameters and focal lengths
Provide additional AR coating options: VIS-EXT, MgF2, VIS 0 °, VIS-NIR, NIR I, and NIR II
A biconcave lens consists of two inward facing, identical curved surfaces and has a negative focal length. They are used to create reduced images or diverge light rays, with all diameters measured in millimeters.
