Multiple Order Waveplate — 25.4 mm
A 25.4 mm multiple-order waveplate in laser-quality crystal quartz. Because its retardation is the desired fraction plus an integer number of waves, it is the most temperature- and wavelength-sensitive of the waveplate types — and performs best in stable, monochromatic laboratory use. AR-coated on both faces, unmounted or in a 30 mm anodized ring. Dual-wavelength versions available.
$350
per waveplate · mounted $370
