Low Order Waveplate
Its properties are much better than the multi-order waveplate because of its thinner thickness (less than 0.5mm). Better temperature (380C), wavelength (1.5nm) and incident angle (4.50) 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
