Introduction:
Optical lenses are optical components designed to focus or diverge light, they can be designed of materials with BK7, UVFS, CaF2, MgF2, Sapphire, Ge, Si, ZnSe etc., We can supply various types of lens including Cylindrical lens Plano Concave/Convex lens, Double Concave/Convex lens, Spherical lens, Aspheric Lenses, Bi-Concave/Convex Spherical lens, Meniscus Spherical lens, also customized lens is available, many of the lenses are offered with a variety of coating options for the UV, visible, or IR spectrums. At present, we can offer the max lens dimensions with dia300x80mm.
Applications:
They are used in a wide variety of applications from microscopy to laser processing, including life sciences, imaging, industrial, and defense field etc., in IR optical system, Germanium, Silicon, and ZnSe lenses are ideal for transmitting the Infrared spectrum, and Fused Silica lens is well suited for the Ultraviolet.
