Plano Concave Lens
Plano Concave Lens

  • Crysmit have more than 10 years of experience in lens manufacturing, design, and optical precision assembly. CRYSMIT provide these lenses with the material of N-BK7, fused silica, sapphire, CaF2, and other glass raw material. 

  • A Plano Concave Lens is a simple optical lens with one flat (plano) and one concave surface. Its primary function is to diverge, or spread out, light rays. They form virtual images and have a negative focal length, indicating they diverge light rather than focusing it. These lenses can also reduce the spherical aberration caused by other lenses.

Know about the Features and application of Plano Concave Lens ?

  • A Plano Concave Lens is a simple lens with one flat (plano) surface and one concave surface. This type of lens is primarily used to diverge, or spread out, light rays. Here are some key features:


  • Diverging Light: Plano Concave Lenses are designed to diverge light. They take parallel light rays and spread them out.


  • Forming Virtual Images: Unlike Plano Convex Lenses, which can form real images, Plano Concave Lenses form virtual images that appear to be located on the same side of the lens as the light source. This makes them useful in applications such as beam expanders and projection systems.


  • Negative Focal Length: These lenses have a negative focal length, which refers to the fact that the lens diverges light rather than focusing it.


  • Reduction of Spherical Aberration: When used appropriately, a Plano Concave Lens can be used to reduce the spherical aberration produced by other lenses.


  • Material Variety: Similar to Plano Convex Lenses, Plano Concave Lenses can be made from a wide range of materials, including N-BK7, Fused Silica, CaF2 and various types of plastic.
