Broadband Quartz Waveplate / WPQW-IR-2M
Air spaced two piece waveplates are suitable for use with high-energy lasers (no optical contact occurs). These products utilize birefringence of quartz and give phase difference of λ/4 (π/2, 90°) or λ/2 (π, 180°) to the input beams. λ/4 retarders convert linearly polarization to circularly and circularly polarization to linearly. λ/2 retarders convert the direction of polarization arbitrarily.

◦Air spaced type waveplates are zero-order (first-order) retardation plates (phase plates) which are assembled from pairs of crystalline quartz plates and are mounted on aluminum frames.

Guide | ▶Custom-made air spaced broadband quartz waveplates for other wavelengths are also available |
Attention | ▶These products can be used for the beams which wavelengths are in +/−1% of rated wavelength. ▶The surface flatness is the reflected wavefront distortion of the surface before coating. ▶Be sure to wear laser safety goggles when checking optical path and adjusting optical axis. |
