CRYLINK quartz true zero quarter wave plate is made of a single quartz crystal. Its thickness is in micron level and its mechanical strength is low, but it allows a larger incidence angle. When a beam of linearly polarized light is perpendicularly incident on a wave plate made of uniaxial crystal, it is decomposed into o-ray and e-ray propagating along the original direction but perpendicular to each other, and the corresponding refractive index is no,ne . Due to the different velocities of the two kinds of light in the crystal, the phase delay is δ=(2π/λ)|no -ne |*d after passing through the wave plate with thickness d. Among them, |no -ne |*d is the optical path difference, the optical path difference generated by the quarter wave plate is (2m+1)λ/4, the phase delay is δ =(2m+1)*π/2, m is a non- negative integer, and m of the quarter wave plate of the true zero order is 0. CRYLINK quartz true zero quarter wave plate is often used to convert linearly polarized light into circularly polarized light. Compared with quartz multi-stage wave plate, quartz true zero wave plate is insensitive to temperature and incident angle, which is suitable for high-power scenes.
