Does your super achromatic quarter wave retarder (SA-QW) really out perform other polymer QWs?

Yes. Our standard SA-QW operates over 410nm – 700nm and from 0 to 45 angle of incidence. Both the wavelength and AOI can be increased with a custom design.
Yes. They do operate like other zero order retarders.
