Polarimeters Manufacturers

Polarimeters are instruments used to measure the rotation of the plane of vibration in polarized light. Polarimetry of thin films and surfaces is called ellipsometry, which is used to provide information about layers that are thinner than the wavelength of the light itself, down to a single atomic layer or less. The most sensitive polarimeters are based on interferometers; while more conventional polarimeters use polarizing filters, wave plates or other devices.
