Plano-Concave Lenses
Plano-Concave Lenses
Plano Concave Lens, 40mm Dia. x -63.5mm FL, AR Coated R<0.25%@780nm, N-BK7 Lens
The Plano-Concave Lens have one flat surface and one concave surface. They have a negative focal length and are used to diverge incoming light, or to increase focal length in an existing optical system. They can be used in beam expanders and projection systems.Moredetailsabout Plano-Concave Lenses，OpticalLenses，optical Coatings， Prism，OpticalMirror，PrecisionOptics，pleasecontactus.CLZ Precision Optics specialize in manufacturing optical components from customer supplied designs, including a wide variety of Plano Concave Lenses. We can provide Featuring surface accuracy to less than 0.2 fringe measured at 633nm and finishes to 20-10 scratch-dig per MIL-PRF 13830, the material are fabricated from quartz, optical glass, silicon, etc. and the sizes up to 200mm diameter.
