Super Large 3" Zero Order Waveplate — 76.2 mm
A super-large zero-order waveplate for large-beam laser techniques. The air-spaced construction permits operation at higher power levels than contacted or cemented plates, with ¼ or ½ wave retardation provided for each wavelength. Specify any wavelength from 355 to 2021 nm. A rugged 4-inch heavy-duty aluminum mounting ring — with retaining ring and scribed crystal axis — is available.
