Achromatic waveplate
Achromatic waveplate is similar to zero order waveplate except that the two plates are made from different birefringent crystals. Since the dispersion of the birefringence of two materials is different, it is possible to specify the retardation values at a broad wavelength range. So, the retardation will be less sensitive to wavelength change. In other words, it can be used at a broadband wavelength range.
- Epoxy Cemented or Air Spaced available
- Very Broad Bandwidth
- Custom size available
- RoHS Compliant
