Double Concave Optical Lens
The double concave lens diverges a parallel beam of light from a point source to produce an upright, virtual image. These lenses are used in optical systems to reduce image size, increase focal length, or correct for aberrations.

Product Overview
Double Concave Optical Lens
This high-precision double concave lens is engineered for beam divergence, image reduction, and expanding light beams. Manufactured from grade A optical glass or fused silica, it features precision-polished surfaces designed to minimize distortion and maximize light transmission. It is an essential component for applications requiring negative focal length and precise optical correction, such as laser systems, telescopes, and scientific instruments.
