Air Gap Waveplate 25.4mm (1 inch) Diameter Wavelength 257nm λ/2
WPQG-25.4C-2570-2M
Air spaced two piece waveplates are suitable for use with high-energy lasers (no optical contact occurs).For Nd-YAG lasers and Yb lasers, there is a lineup from fundamental to 4th harmonic.
◦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.
◦Custom-made air spaced type waveplates for other wavelengths (248nm, 257nm, 308nm etc.) are also available.
