Quartz True Zero-Order Quarter-Wave Plate TWP10Q-780Q
Quarter-wave plates convert between linear and circular polarization to control lasers or other narrowband sources. JCOPTIX quartz true zero-order plates use a single high-quality crystal of micrometer thickness and relatively low mechanical strength, introducing a quarter-wavelength optical path difference. Compared with ordinary plates, they are less temperature- and angle-sensitive, have higher damage threshold, and permit larger angles and power. Standard housings have SM05 external threads for 10 mm clear-aperture plates, fitting mounts such as MMR-05T. A proprietary gasket at the thread base aligns polarization to a chosen scale. 1. Screw fully into the SM05 mount and lock rotation if required. 2. Compare the white fast-axis mark to the desired 0° or 90° scale. 3. Gently continue turning the protruding housing to align, with about 60° adjustment. The plate cannot be removed from its housing, engraved with model, design wavelength, and fast axis.

Low-Order Waveplate WPL210 Waveplates Zcoptic
Retardance [Low-Order Waveplate; All Standard Products Use Quartz]: λ/2 Diameter [Low-Order Waveplate; All Standard Products Use Quartz]: 10.0 mm Standard Mount Diameter [Low-Order Waveplate; All Standard Products Use Quartz]: 25.4 mm
Multiple-order wave plates made from quartz or MgF2 are available; standard products are quartz. Any operating wavelength from 150-7000nm can be selected. Low-order wave plates consist of a single quartz or MgF2 crystal plate, using the optical path difference between the O and E rays to obtain the required phase retardance. Compared with zero-order wave plates, low-order wave plates have a simpler structure and lower cost, making them suitable for high-volume industrial applications. Their single-plate structure provides a high damage threshold. Features: single-plate construction; customizable wavelengths from 150-7000nm; antireflection coatings on all surfaces; high damage threshold; low price. Processing specifications: standard wavelengths of 266nm, 355nm, 532nm, 632.8nm, 780nm, 808nm, 980nm, 1064nm, 1310nm, and 1550nm. Standard low-order wave plates.
