UV Fused Silica Plano-Concave Lenses

Plano concave lens is diverging lens. One of it's surface is flat whhile the other is an inwardly concave spherical surface.   The characteristic of concave lens is the edge are thick and the center is thin, therefore,it can not converge the light into a real image but instead causes the light to diverge outward   Properities Negative focal length, after light passes through,it spreads out and appears to originate from a "virtual focus" in front of the lens Imaging characteristics, it can only form a upright and magnified virtual image, and this virtual image is located on the same side as the object with respect to the lens, it can not be projected onto a screen and can only be observed through the lens.   Main purpose   Commonly used various applications including high precesion laser optics, medical image reduction,microscopy, telescopes and beam expansion etc   CCRQ can supply spherical lens including plano-convex lenses, double convex lens, plano-concave lenses, bi-concave lenses,…
