Low-order Waveplate

Low-order waveplate properties is 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 than Zero-order waveplate.
