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.

Details

◦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.

Name	Broadband Quartz Waveplate 30mm Diameter Wavelength Range 650 - 780nm λ/4
Weight	0.0110kgs
Standard Coatings Available	No
Guide	Custom-made air spaced broadband quartz waveplates for other wavelengths are also available, contact our Sales Division with you requests. Standard thickness of Aluminum frame is 6mm (subject to differ without notice). Optical axis is parallel to the edge of 14mm squared plate.
Remark	-
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.
