Polarization precision optics is a specialized class of optical components designed for high-accuracy control of light polarization state and characteristics in scientific, industrial, and laser systems.
Polarization precision optics includes elements such as high-precision polarizers, bandpass filters, prisms, and other devices that provide exceptional polarization filtering and control. These components are manufactured from materials with high optical homogeneity and minimal losses, making them suitable for systems requiring maximum accuracy and parameter stability.
Our company offers services for the production of polarization cubes.
Polarization cubes consist of two cemented AR-90 prisms with a thin-film multilayer polarization coating applied to the hypotenuse.
Their operating principle is based on the selective transmission or refraction of light with a specific polarization.
The production of polarization precision optics combines advanced technologies: from material selection and processing to the formation of microstructures and the deposition of complex coatings, ensuring exceptional accuracy and stability of optical properties.
Main functions and advantages
- Wide wavelength range. Modern filters and polarizers can operate across a broad spectral range, including ultraviolet, visible, and infrared regions.
- High resistance to laser radiation. Thanks to material and coating quality, such components can withstand intense laser radiation.
- Minimal optical distortion. High-precision manufacturing ensures low scattering, no beam deviation, and no wavefront distortion.
- Function integration. Modern solutions can combine the properties of a polarizer and a bandpass filter in a single component, simplifying optical designs and improving system efficiency.
Applications
- Optical communication. Improving signal-to-noise ratio in laser communication systems through interference filtering.
- Laser systems. Polarization control in high-power lasers for cutting, welding, and medical procedures.
- Scientific research. Analysis of birefringence in crystals and biomaterials using microscopes.
- Space and defense technology. Use in guidance systems and satellite optics.
