31 May 2016 Unlike standard waveplate, Achromatic Waveplate( 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.The Retardation tolerance of our AWP is better than λ/100 over the entire wavelength range.The flat response of an AWP is ideal for use with tunable lasers,multiple laser-line systems and other broad spectrum sources.
