The 10RP22-05 Dual Wavelength Multiple-Order Wave Plate is a crystal quartz optic designed to differentially retard the phase of a polarized beam. With the proper phase shift, this wave plate can rotate the direction of polarization or convert linear into circular polarization. This 532 and 1064 nm antireflection coated 1 inch (25.4 mm) diameter multiple-order wave plate has λ/2 (180°) retardation. When using multiple-order wave plates, several items should be considered. A wave plate of practical thickness produces a multiple of λ/4 or λ/2 retardation (i.e. 15 1/2 λ for about 1 mm thickness). Higher orders cause retardation to vary dramatically with wavelength. Wave plates are sensitive to temperature changes. A typical multiple-order wave plate has a temperature coefficient of 0.0015λ/°C, compared to 0.0001λ/°C for a zero-order wave plate, so tighter temperature control will be required. Precise adjustment of retardation is possible by tilting the wave plate. Tilting about the slow axis increases retardation, while tilting about the fast axis reduces retardation.

旋转偏振方向或将线性偏振转换为圆形偏振。这532和1064海里防反射涂层1英寸(25.4毫米)直径多级的波板λ/ 2(180°)缺陷。在使用多阶波板时，应考虑几个问题。一波板的实际厚度产生λ/ 4的倍数或λ/ 2缺陷(即15 1/2λ约1毫米厚度)。较高的阶数会引起阻滞随波长的显著变化。波板对温度变化很敏感。一个典型的多级的波板的温度系数0.0015λ/°C,相比0.0001λ/°C零级波片,所以需要更严格的温度控制。通过倾斜波板可以精确地调整减速。慢轴倾斜会增加减速，而快轴倾斜会减少减速。
