Quartz waveplate
WebAchromatic Quartz-MgF 2 Zero-Order Wave Plates consist of crystalline quartz and magnesium fluoride (MgF 2) crystals, each with a highly efficient broadband antireflection coating, in an air-spaced design. This construction ensures excellent transmitted wavefront quality, while minimizing beam deviation and surface reflection losses. WebAt any specific wavelength, the phase difference is governed by the thickness of the retarder (waveplate). Half (λ/2) waveplate. A linearly polarized beam incident on a half-wave crystal quartz waveplate emerges as a linearly polarized beam, but is rotated such that its angle to the optical axis is twice that of the incident beam.
