Zero order wave plates are made of two multiple-order wave plates with their optical axis aligned perpendicular to each other. The effect of the first plate is cancelled by the second, except for the residual difference between them. These zero-order wave plates provide quarter-wave retardation at their design wave lengths and are made by air-spaced design for high damage threshold. Zero order wave plates are much less sensitive to wavelength and temperature changes. All plates are AR coated to increase transmission at their design wavelength.
