Research Grade Stokes Polarimeters
Please see Hinds' PolSNAPTM Stokes Polarimeter page for more information on compact Polarimeter solutions.
Hinds Instruments’ Stokes Polarimeter Systems offer unparalleled sensitivity for measuring the polarization state of a light beam or source. Using a robust, refined technology, our Dual PEM Stokes Polarimeters quantify all 4 normalized Stokes vectors with a single measurement and no moving parts. The excellent sensitivity, repeatability and straightforward operation of the Dual PEM Stokes Polarimeter platform have made this system invaluable to challenging applications in optical component characterization, astronomy, fiber optic research and manufacturing, and laser quality control.
- Research Grade
- No moving parts
- No imprecise, noise-generating rotators
- High speed modulation ( > 40 kHz )
- Fast: > 100 normalized Stokes parameter sets per second
- Instantaneous, simultaneous complete data capture and display
The measured light can be from a laser, a fiber, a broadband source or an astronomical body like the sun or a star. The system measures and instantaneously displays the value of each of the normalized Stokes parameters, as well as the position on the Poincare´ sphere. The displays DOP, DOLP and DOCP.
The turnkey system includes optics and electronics in one module, a complete software package, and a PC with monitor. The system, which utilizes two photoelastic modulators (PEMs), generates all 4 Stokes parameters with a single measurement. Various standard options are available, including versions for single wavelength or spectroscopic measurements. Systems are available for the visible, NIR, IR and UV. The software package is designed to calibrate the PEMs for changing wavelengths and a fiber optic input is available. The electronic signals are processed through lock-in amplifiers.
