Source: B.Halle The Berek Compensator: A Versatile Tool for Tunable Phase Retardation Overview of Berek Compensator A Berek compensator, named after German physicist Max Berek, is a type of tunable phase retardation plate. Also known as a Berek waveplate or Berek tunable retarder, it is made of a single uniaxial birefringent crystal with its extraordinary […]

Source: Edmund Optics Understanding Retardance in Optics Understanding Retardance in Optics What is Retardance? Retardance refers to the difference in optical phase shifts experienced by different polarization components of a light beam propagating through a birefringent medium. It is measured in radians (rad) or degrees (°), or in terms of wavelengths. Applications of Retardance in

Source: Wikipedia The Babinet–Soleil Compensator: An Adjustable Waveplate A Babinet–Soleil compensator is a device that consists of three birefringent plates made from the same material, typically crystalline quartz. It is used as an adjustable waveplate, also known as a retarder plate. Functionality of the Compensator The compensator contains one plane-parallel plate and two wedges, with
