Waveplates
25.4 mm zero order waveplates
The 30 mm zero order waveplates provide users with a high-power crystalline quartz retarder with a free aperture of 25.4 mm. The waveplates are air spaced and have a stainless steel spacer between two crystalline quartz plates, which form the zero order capability. They are much less sensitive to temperature fluctuations than multiple order waveplates and have a higher thermal stability and power draw than contacted or cemented waveplates.
