Low Order Waveplate
Low Order Waveplatesare much better than the multi-order wave-plates because of its thinnerthickness less than 0.5 mm). Better temperature(~36°C), Wavelength(~1.5 nm) and incident angle(~4.5°) bandwidth and high damage thresholdmake it widely used in common application. Also it is economical.
