Waveplates

Quartz Waveplates Birefringent elements made of optical synthetic fused silica crystal introducing a phase difference (λ/4 or λ/2) between orthogonal polarization components.

Quartz Depolarizers Elements for converting a polarized beam into a depolarized beam.

Air Gap Type Waveplates Two-piece-type waveplates compatible with high-energy lasers (no optical contact occurs).

Broadband Quartz Waveplates Air-gap-type two-piece waveplates compatible with high-energy lasers (no optical contact occurs).

Mica Waveplates Birefringent elements made of natural mica introducing a phase difference (λ/4 or λ/2) between orthogonal polarization components.

Fresnel Rhombs Retarders Elements introducing a phase difference (λ/4 or λ/2) between orthogonal polarization components using internal reflections.

Custom-made Waveplates Also available are custom wave plates made to the size (external dimensions), shape, wavelength, and other specified parameters.
