The 05RP14-16 Multiple-Order Quartz Wave Plates is a crystal quartz optic designed to differentially retard the phase of a polarized beam. With the proper phase shift, this waveplate can be used to convert linear polarization into circular polarization. This 1/2 inch (12.7 mm) diameter wave plate is 1mm thick and has λ/4 (90°) retardation. It is antireflection coated to maximize transmission at 532 nm. 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. 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.

05RP14-16多阶石英波片是一种石英晶体光学器件，用于不同程度地延迟偏振光的相位。在相移适当的情况下，该波板可以将线偏振转换为圆偏振。这波片1/2英寸(12.7毫米)直径是1毫米厚,λ/ 4(90°)缺陷。它是防反射涂层，以最大限度地传输在532纳米。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阻滞。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。
