LaVision Polarization Rotator
A Lavision Polarization Rotator is an optical component that turns the polarization axis of a linearly polarized laser beam by a chosen angle. LaVision the German maker of laser based imaging and flow diagnostics systems such as PIV and LIF supplies accessories like this for setting up and controlling the polarization of laser light in measurement setups. It lets the user match the beam polarization to a crystal, beam splitter, optic, or measurement requirement without rebuilding the optical path.
Key Features
- Controls beam polarization: rotates the polarization of linearly polarized light by a set angle typically 45° or 90° for fixed rotators or adjustable by rotating a waveplate on a motorized or manual mount
- Optimizes optical throughput: helps match polarization to beam splitters, polarizers, harmonic generation crystals, and other polarization sensitive optics
- Useful in laser diagnostics: supports setups such as PIV, LIF, Mie scattering, and Raman measurements where polarization affects signal level and contrast
- Helps with beam steering and combining: allows two beams to be combined or separated using polarizing optics
- Precision optical construction: made from optical grade materials with coatings suited to the laser wavelength as is usual for this class of component
- Rugged mounting: designed to sit in an optical beam path with standard mounts alongside other laser optics
Typical Applications
- Laser based flow diagnostics (PIV, LIF, and related imaging techniques)
- Polarization dependent spectroscopy and scattering measurements
- Beam conditioning, combining, and splitting in laser setups
- Matching laser polarization to crystals and optical components
- Research and teaching optics labs
Why Choose It
A Lavision Polarization Rotator is a simple reliable way to tune a laser beam polarization without rearranging the beam path. It helps make measurements cleaner and more efficient so the rest of the optical system performs as designed.
