Product Details

Double-Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths. Double-Concave 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.

Opticreate offers AR coated and Uncoated lenses, Anti-reflection coatings range from the Ultraviolet (UV) to the Infrared (IR), Germanium (Ge), Silicon (Si), or Zinc Selenide (ZnSe) substrates are ideal for Infrared (IR) applications and Fused Silica are used for UV applications,UV Fused Silica or Calcium Fluoride (CaF2) substrates are also available for additional performance in the Ultraviolet (UV) or Infrared (IR) spectrums. Calcium Fluoride (CaF2) offers a very wide transmission range of 350nm - 7μm. Opticreate’s Double-Concave Lenses are available in a wide range of diameters or focal lengths.  We also supply Fire Alarm Infrared Optical Lens, Infrared Optical Lens For Navigation.
