Plano-Concave Lenseshave negative focal lengths. These lenses diverge collimated incident light. They form virtual images which are seen through the lens. They are often used to expand light or to increase focal lengths in existing systems.Materail:BK7,Fused Silica,Calcium Fluoride,Zinc Selenide and othersFocal Length Tolerance:+/-1%DiameterTolerance:+0.0,-0.1mmCenter Thickness:+/-0.1mmSurface quality:40-20Centration:90%Protective BevelWe will also do according to the specifications such as size, structure, material, surface treatment and so on that the customers required. We supply them with good quality and low price. Please contact us to know details. Besides, there are a large volume of optical components in various shapes and sizes in stock to facilitate quick deliveries.
