Introduction:
When a light beam in certain polarization state goes through Single Synthetic Crystal Quartz along the optical axis, its polarization vectors rotate at an angle, which is the product of the distance it travels and the rotatory power. Quartz thus can be fabricated into optical rotators. Quartz’s rotatory power is corellated with the wavelength of the light beam. The shorter the wavelength, the higher the rotating power. Quartz rotators are mostly used for light with wavelength short than 1550nm.
This material is usually right handed (dextro-rotatory), which means that as you look at the source from the image plane the polarization appears to rotate clockwise as it propagates through the crystal. Where required we can also supply left-handed (levo-rotatory) components where the direction of rotation is reversed. We can also manufacture parts from quartz crystals for particular applications.
The features of our products are
- High damage threshold, AR coated
- Professional supplier / manufacturer
- Custom or large aperture
Our components are manufactured from the high optical quality synthetic materials, which offer excellent repeatability.
