Plano concave Lenses have one concave surface. It has negative focal length. It is often used to expand light or to increase focal length in existing systems.

Lenses have the functions of converging, diverging, and shaping beams in the optical path. Planar convex lenses (PCX)/biconvex lenses (DCX) converge the light rays; PCV/DCV lenses diverge light rays. Optical Glass Lenses are optical components that are transparent to certain light spectrums, and oriented for either collecting or diverging light. The functions of optical lenses encompass laser processing, image magnification, fiber collimation, etc. and the applications of Optical Glass Lenses are extensive, ranging from life science, and medical diagnoses, to defense and industrial production.

With over ten years of experience, Shandong Yanggu Constant Crystal Optics is capable of providing high-precision Lenses for high-end applications.
