2023 Plano-Concave Lens Optical Mirror Spherical Imaging Experimental Equipment Coated with OEM/ODM Service
A plano-concave lens is a lens that has a flat surface on one side and a concave surface on the other side. The focal length of a plane-concave lens is negative, allowing the beam to diverge. Therefore, it can be used in optical system for beam expansion, light projection or to increase focal length.
Oplens can not only customize the plano-concave lens with common materials of N-BK7 (Shott) and fused silica, but also customize the plano-concave lens of any glass material.

How does concave lens work?
The plano-concave lenses are used to expand light beams or to increase focal lengths in optical systems. 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.
Oplens (brand own by SiChuan JUKA Optical Technology) is located in the city of Chengdu, China, which enjoys the reputation of the world optical processing center.
