Multiple Order Waveplates

Ealing Multiple Order Waveplates are available in a range of laser-line wavelenths, mounted in a 25.4 mm diameter mount. Multiple Order Waveplates are sensitive to changes in temperature, angle of incidence, and degree of collimation. They are intended for use at the design wavelength only. If used at a different wavelength, a retardation change of 10% occurs for every 0.2 nm deviation.
