Our true zero order waveplates are precision polished to a zero order retardance thickness. This results in a waveplate with the least sensitivity to wavelength, temperature, and angle of arrival. The thickness of a waveplate is determined by the desired retardance, operating wavelength, and the birefringence of the material. A true zero order quartz waveplate is typically very thin (i.e. quarter wave at 633nm is only 17.5μm thick). However, due to the change in birefringence with wavelength, a practical thickness can be achieved only at longer wavelengths. We offer l /2 and l /4 wave true zero order waveplates at the popular telecom wavelength, 1550nm (note: the l /4 wave can be used like a quarter waveplate with a sign reversal). |
