Dia12.7mm EFL-200mm UV Fused Silica Plano Concave Lens Uncoated, Code: 1104-063
Plano-concave Lens is a bulk optical component with a flat side and an inward convex side, which contribute to a negative focal length. Plano concave lens diverges collimated light beams according to a virtual focusing point and could be used to spread a collimated light beam, collimate focused light, increase the focal length of an optical system, or condense images.
Hangzhou Shalom EO presents off-the-shelf and custom Plano Convex lenses made from the Corning UV Fused Silica ( Corning 7980-0F, 7980-1D) or its equivalent with a broad range of focal lengths and dimensions, both coated versions and custom-tailored coatings (BBAR coating, V coating, etc.). This page highlights the standard JGS1 plano concave lenses with lambda/4 irregularities and 40/20 Scratch/Dig, while UVFS plano-concave lenses with higher precisions are also obtainable (lambda/10 irregularities, 10/5 S/D).
