Plano-Convex Lens is widely use in optical display systems, projection optics systems, imaging optical systems, and laser measurement systems. It is best use where conjugate point-- object distance, S or image distance S' is more than five times of the other. This lens is almost the most super form for both collimating a point source and focusing collimated light.
We can manufacture various shape and special material Optical Lens, such as Plano-Convex Spherical Lens,Plano-Concave Spherical Lens,bi-convex Spherical Lens,bi-concave spherical lens,Meniscus Spherical Lens,special spherical lens,Achromatic Lens,ball lens,sphere lens etc. Diameter from 1mm upto 300mm, depends on the detailed specification.
