Product Description

Ultra-broadband Optical Lens  Telescope Medical Scientific Research Instrument Double Concave Lens

 
 

Product Description

 

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.
