Tunable Liquid Crystal Phase Retarder, With Compensation LVVH-T4C
JCOPTIX compensated tunable liquid-crystal retarders combine high-quality antiparallel cells, nematic material, and polymer compensation plates in one-inch housings with BNC cables. External AC rapidly tunes retardance from -20 nm to λ/2 or -20 nm to λ for precise polarization/phase control. Operation: 0-45 ℃. Three bands: 400-700 nm, 650-1100 nm, 1050-1700 nm for visible/NIR. In uncompensated cells, PI-surface anchoring prevents nearby molecules reorienting under voltage, leaving ~30 nm residual retardance even at high drive. A low-retardance compensation plate with slow axis perpendicular to the cell's slow axis cancels retardance over 0-25V, enabling zero retardance within the operating range. Two series are provided: half-wave, -20 nm to λ/2; full-wave, -20 nm to λ. Both offer adjustable retardance, fast response, and broad temperatures, with model selection/customization. Active devices require AC; DC charge accumulation causes damage. Recommended: 1-2 kHz, 0-±25 V, 50% duty, square wave. Above 25 V may degrade/damage cells. Compensated half-wave retarders. Models: LVVH-T2C, LVVH-T3C, LVVH-T4C. Range: -20 nm to λ/2. Temperature: 0-45 ℃. Bands: 400-700 nm, 650-1100 nm, 1050-1700 nm. JCOPTIX offers bands 400-700 nm, 650-1100 nm, 1050-1700 nm, with AC tuning over -20 nm to λ/2 and high aperture-wide uniformity. Fast response/broad temperatures; see manual. Housings fit Ø1 inch holders and mark slow-axis direction. Compensated full-wave retarders. Models: LVVF-T2C, LVVF-T3C, LVVF-T4C. Approximate range: -20 nm to λ. Temperature: 0-45 ℃. Bands: 400-700 nm, 650-1100 nm, 1050-1700 nm. JCOPTIX offers bands 400-700 nm, 650-1100 nm, 1050-1700 nm, with AC tuning over -20 nm to λ and high aperture-wide uniformity.

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.
