Achromatic waveplate

Achromatic waveplate is made of two or more matched birefringent crystals, where the retardation changes are minimized as the wavelength changes. These achromatic waveplates are used for tunable lasers, multiple laser-lines and other broad spectrum sources. Super-achromatic waveplate consists of three achromatic waveplates based on Pancharatnama's design is used for modulator in polarimeter.


Features of Achromatic waveplate

- Wide spectral bandwidth
- Low temperature sensitivity
- Large sizes available
