Its properties are much better than the multi-order waveplate because of its thinner thickness (less than 0.5mm). Better temperature (38℃), wavelength (1.5nm) and incident angle (4.5°) bandwidth and high damage threshold make it widely used in common application. Also, it is economical for low cost for high damage threshold with thickness 0.2-0.5mm
