Achromatic Waveplates and Retardation Plates
from CeNing Optics Co., Ltd.
Achromatic Waveplates provide a constant phase shift independent of the incident wavelength of light. This wavelength independence is achieved by using two different birefringent crystalline materials. The relative shifts in retardation over the wavelength range are balanced between the two...

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]
