Plano-Concave Lens

Product Details

Plano-Concave Lenses, which have one concave surface, are Optical Lenses with negative focal lengths. PCV Lenses should be oriented with the plano, or flat, surface towards the desired focal plane. Plano-Concave Lenses are ideal for beam expansion, light projection, or for expanding an optical system’s focal length.

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.
