Zero-Order Waveplate, Half-Wave, Quartz, 12.7 mm Diameter, 266 nm

The 05RP02-02 Zero-Order Quartz Half Wave Plate has λ/2 retardation in a 12.7 mm diameter housing optimized for 266 nm. Zero-order waveplates are temperature insensitive phase retarders for moderate bandwidth applications. These zero-order wave plates are constructed of two quartz plates, air-spaced to allow for use with high-power lasers, in a standard 12.7 mm or 25.4 mm diameter housing for easy mounting into a holder. Zero-order wave plates are moderately insensitive to wavelength change, which makes them ideal for laser diode or tunable laser applications. Typical zero-order wave plates have a temperature coefficient of 0.0001 λ/°C.
