Photonchina

Quartz Waveplate
Photonchina is a leading manufacturer of quartz waveplate products in the world.
Our complete quartz waveplate range includes true zero order, zero order, multiple order, with the retardation of half, quarter or octadic wave. Special types like achromatic and dual wavelength waveplate, either in circular or quadratic shape, are all available.
Thickness of true zero order waveplate T=0.027mm, is the latest accuracy level reached, thanks to our special production technique and skilled technicians.

Crystal Polarizer
Giant company and small start-up have all chosen our polarizer products for their applications in laser, telecommunication,surveying or others.
Glan laser polarizer, Glan taylor polarizer, Wollaston polarizer, Glan thomson polarizer etc, made of BBO, YVO4, Calcite crystal, are produced by the team with more than ten years of experience.
High quality crystal materials and excellent optical coating performance have contributed to customer's approval worldwide.
Photonchina offers polarizer with or without mount.

Lenses
You may find various types of lenses from Spherical lenses, Cylindrical lenses to Acylindrical lenses here, produced by materials of BK7, Fused Silica as well as Calcium Fluoride, Sapphire, Silicon and Germanium etc.
