Product overview

Achromatic waveplates is similar to zero order waveplate sexcept that the two plates are made from different birefringent crystals. Since the dispersion of the birefringence of two materials is different. It is possible to specify the retardation values at a broad wavelength range. So, the retardation will be less sensitive to wavelength change. In other words, it can be used at a broad-band wavelength range.
