Quartz Air-Spaced Zero-Order Quarter-Wave Plate ZWP20Q-1310Q
Quartz air-spaced zero-order quarter-wave plates commonly convert linear and circular polarization into each other, controlling polarization from lasers or other narrowband sources. JCOPTIX combines two multiple-order quartz plates with an air gap, suitable for high-power diode and tunable lasers. One plate's fast axis aligns with the other's slow axis, making net retardance the difference between their phase retardances. Compared with multiple-order plates, zero-order plates offer several advantages: reduced wavelength sensitivity, ideal for laser diodes and tunable lasers; reduced temperature sensitivity, since thermal changes in the two quartz plates cancel and retardance changes little over a wide temperature range; and high-power suitability, since the air gap rather than optical adhesive within the clear aperture raises the damage threshold. JCOPTIX standard air-spaced zero-order housings have SM05 external threads for 10 mm clear-aperture plates or SM1 external threads for 20 mm clear-aperture plates. They fit matching internally threaded rotation mounts such as MMR-05T and MMR-1T. JCOPTIX's proprietary rubber washer at the thread base facilitates direct alignment to specific mount angles. Operation is simple and quick: 1. Screw the zero-order plate into the rotation mount until the SM05/SM1 thread reaches its end; lock the rotating part as needed. 2. Check the difference between the fast-axis direction (white housing line) and the target scale mark (0° or 90°). 3. Apply slight force to continue turning the protruding cylindrical part until the white fast-axis line aligns with the target mark. Adjustment is approximately 60°. JCOPTIX offers mounted quartz air-spaced zero-order plates with clear apertures of 10 mm, 20 mm, and 45.5 mm. Housings are engraved with model, design wavelength, fast-axis direction, and other parameters for quick identification. Contact technical support for custom sizes, coatings, or wavelengths.

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.
