Zero order waveplate 460 series

easy to align temperature insensitive moderate insensitive to wavelength made from high quallity optical grade crystalline quartz quarter wave and half wave retardation versions available suitable for high and low power laser applications Rotate the direction of polarization (λ/2) or convert linear into circular polarization or vice versa (λ/4). Zero order wave plates are formed from two thin sections which are polished to different thicknesses to have retardation difference exactly equal to the required. These component plates have orthogonal optic axis directions, so that the roles of the ordinary and extraordinary rays are interchanged in passing from one plate to the other. Retardation error versus wavelength is reduced therefore they are very useful for dye laser or laser diode application. Zero order optically contacted wave plates are supplied mounted and have multilayer dielectric anti-reflection coating on both sides maximising transmission.
