More Info.. |
Plano-concave lenses have a plano flat face and an inward facing concave face. Biconcave lenses have both faces with inwards facing curves. They have a negative focal length achieved by bending input parallel rays so that they diverge away from one another on the output side of the lens. Plano-convex lenses are mainly used for image reduction in beam expanders, tube-length correction lens in microscopy and as a Barlow lens in astronomy. Our surplus concave lenses are mainly listed in BK7 or F2 equivalent materials. High-index materials such as F2 reduce spherical aberration and offers low F numbers. We also list lenses manufactured from UV Grade Fused Silica which works at 175nm.
