Waveplates

Low-order Waveplate

Its properties are much better than the multi-order waveplate because of its thinner thickness (less than 0.5mm). Better temperature (38°C), wavelength (1.5nm) and incident angle (4.5°) bandwidth and high damage threshold make it widely used in common application. Also, it is economical.
