Unlike standard waveplates, Achromatic Waveplates, AWP, provide a constant phase shift independent of the wavelength of light that is used. This wavelength independence is achieved by using two different crystalline materials to yield quarter- or half-wave retardation over a broad spectral range. [See More]
