Biconvex LensesBiconvex lenses are positive focal length elements that both surfaces are outward curved. Bi-convex lenses are popular for many finite imaging applications. This type of lens is best suited for use in situations where the object and image are on opposite sides of the lens and the ratio of the image and object distances (conjugate ratio) is between 0.2 and 5.
Wuhan Especial Optic provides high quality optical lenses in different shapes, like Plano-convex, Plano-concave, Bi-convex, Bi-concave, Meniscus, cylindrical lenses, ball lenses, achromatic doublet lenses etc.We also offer coating deposited service. Such as AR coating, broadband AR coating, dielectric coating, metallic coating and DLC coating (for FLIR spectrum).
Besides OEM and ODM service, we have many kinds of lenses in stock. Let us know your demands, then we can arrange free samples in fast dispatch.
