Quartz True Zero-Order Half-Wave Plate TWP10H-905Q
Half-wave plates rotate linear polarization without changing its intensity, controlling lasers or other narrowband sources. JCOPTIX quartz true zero-order half-wave plates use a single high-quality quartz crystal of micrometer thickness, introducing a half-wavelength optical path difference. Compared with ordinary plates, they are less sensitive to temperature and incidence angle, have higher damage thresholds, 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 rubber gasket at the thread base aligns polarization with the mount scale. 1. Screw the plate fully into the SM05 mount and lock rotation if needed. 2. Compare its white fast-axis mark with the desired 0° or 90° scale. 3. Gently continue turning the protruding housing until aligned, with about 60° adjustment. The wave plate cannot be removed from its housing, which is engraved with model, design wavelength, and fast-axis direction. Contact technical support for custom dimensions, coatings, or wavelengths.

High-Power Variable Optical Attenuator VBA0120-355 Waveplates U-optic
Type: Transmissive Design Wavelength: 355 nm Clear Aperture Dimension: 14mm
A high-power variable optical attenuator consists of one or two thin-film polarizing beamsplitters and a zero-order half-wave plate. Rotating the half-wave plate continuously changes the transmitted fraction of the output light. Transmission and reflection versions are available. The transmission version provides a dynamic attenuation range from 0.5% to 95%; the reflection version provides a range from 0.25% to 99%. High-power variable optical attenuators are primarily used to adjust output power in high-power environments.

Waveplate Waveplates 100optics
Transmission range [General page-top description, without specific subtype/material identification]: 330-2100 nm Coefficient of Thermal Expansion [General page-top description, without specific subtype/material identification]: 7.5x10⁻⁶ Density [General page-top description, without specific subtype/material identification]: 2.51 g/cubic centimeter
Waveplates are made from birefringent materials. The speeds of the o ray and the other ray through the material are inversely proportional to their refractive indices. Their speed difference produces a phase difference when they recombine; at a particular wavelength, this is determined by the retarding thickness. Transmission range: 330–2100nm. Thermal-expansion coefficient: 7.5 x10⁻⁶/K. Density: 2.51g per cubic centimeter. Half-wave plates: thickness gives a phase difference of L/2 wavelengths for true zero order, or multiples of l/2 wavelengths for multiple order. A linearly polarized incident beam remains linearly polarized, but its angle to the optical axis is twice the incident angle. A half-wave plate therefore acts as a continuously adjustable polarization rotator, used to rotate the polarization plane, for electro-optic modulation, and with a polarizing cube as a variable-ratio beamsplitter. Quarter-wave plates: thickness gives a phase difference of L/4 wavelengths for true zero order, or multiples of l/4 wavelengths for multiple order. When the angle q between the incident electric-field vector and the retarding principal plane is 45, the output is circularly polarized. Double passage by mirror reflection makes a quarter-wave plate act as a half-wave plate, rotating the polarization plane through a particular angle. Applications include generating circular or linear polarization from circular or elliptical states, optical pumping, suppressing unwanted reflections, and optical isolation.
