The 10RP02-24 Zero-Order Quartz Wave Plate is a temperature insensitive phase retarder for moderate bandwidth applications. This zero-order wave plate is constructed of two quartz plates, air-spaced to allow for use with high-power lasers. The assembly is held in a 1 inch (25.4 mm) diameter black anodized aluminum housing to protect the optic and permit convenient handling and mounting. The wave plate is antireflection coated to maximize transmission at the 632.8 nm wavelength, and has a λ/2 retardation. Retardation in zero-order wave plates is insensitive to temperature since thermal changes between the multiple-order wave plates tend to cancel. A typical zero-order wave plate has a temperature coefficient of 0.0001 λ/°C compared to 0.0015 λ/°C for a multiple-order wave plate, providing less change in retardation over an extended temperature range. Zero-order wave plates offer several distinct advantages over multiple order wave plates. The primary benefit is a moderate insensitivity to wavelength change, making them ideal for laser diode or tunable laser applications. For example, a zero-order wave plate designed for 780 nm will provide useful retardance from 765–795 nm. By combining two wave plates whose retardations differ by exactly λ/4 or λ/2, a true λ/4 or λ/2 wave plate results. The fast axis of one plate is aligned with the slow axis of the other, so that the net retardation is the difference of the two retardations.

10RP02-24零阶石英波片是一种温度不敏感的相位延迟器,适用于中等带宽的应用。这个零阶波板是由两个石英板构成的,间距允许与大功率激光器一起使用。该总成采用直径1英寸(25.4 mm)的黑色阳极氧化铝外壳,以保护光学元件,便于操作和安装。波板是在632.8纳米防反射涂层最大化传播波长,和有一个λ/ 2阻滞。零阶波板的迟滞对温度不敏感,因为多阶波板之间的热变化往往相互抵消。典型的零级波片的温度系数0.0001λ/ 0.0015°C比λ/°C多级的波板,提供更少的缺陷在延长的温度变化范围。零阶波板比多阶波板有几个明显的优点。其主要优点是对波长变化不敏感,使其成为激光二极管或可调谐激光应用的理想选择。例如,为780纳米设计的零阶波板可以提供765-795纳米的有效延迟。通过结合两个波板的缺陷完全不同的λ/ 4或λ/ 2,一个真正的λ/ 4或λ/ 2波片结果。一个板的快轴与另一个板的慢轴对齐,所以净延迟是两个延迟的差值。
