    • Silicon Plano-convex Lens

    Silicon plano-convex lens is a positive lens used for beam expansion, imaging, beam collimation, focusing collimation, beam collimation point light source, and other purposes. A flat convex lens with one convex surface and one flat surface, with a positive focal length, is commonly used for applications such as reducing beam size, reducing focal length, or enlarging images. UM OPTICS can provide a diameter of 2-300mm and a thickness of 0.12-60mm (accuracy can reach 20-10,1)/ 10L@633nm ）The silicon flat convex lens can be coated with MgF2, UV-AR, UV-VIS, VIS-EXT, VIS-NIR, NIR I, NIR II, Telecom NIR, SWIR, SWIR, YAG-BBAR and other film systems.
