Double-Concave Lenses, also known as DCV or Biconcave Lenses, are used in beam expansion, image reduction, or light projection applications. These lenses are also ideal for expanding the focal length of an optical system. Double-Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths.

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. Oplens has been committed to providing customers with high-precision optical system solutions over 16 years, covering the complete manufacturing process from the design, processing and assembly of various optical components and mechanics.
Oplens equipped Precitech SPDT with Taylor Hobson PGI 3D profilometer. The results of the profilometer measurement system can be directly put into the diamond machine to provide positive compensation values for the machining of aspheric components. At the same time, curvature, surface flatness, roughness and other indicators can be quantified effectively and accurately.
