Fuzhou Siaon Optoelectronic Technology Co., Ltd. provide Achromatic waveplate Achromatic waveplate is similar to zero order waveplate except 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 broadband wavelength range.  Material: Quartz+MgF2 Dimension Tolerance:+0.0, -0.1mm Clear Aperture: >90% Wavefront Distortion: λ/4@632.8nm Surface Quality: 40-20 Parallelism:< 10 arc sec Retardation Tolerance: λ/100 Coating: AR Coating Mount:Black Anodized Aluminum
