Description

Détails

Because of difference in dispersion in these uniaxial positive crystals it is possible to calculate thickness of each plate so that birefringent phase shift in assembly changes very slowly over certain wavelength range. This is a way to obtain achromatic zero order waveplates.

Mounted achromatic (broadband) half-wave and quarter-wave retardance waveplates are available for several bands in the wavelength range of 460-1700 nm. Air-spaced construction enables to use of these waveplates for high-power applications. These waveplates are ideal for multiple wavelengths and broadband operation, due to their constant retardance over a particular broad wavelength range.
