Zero order · crystal quartz
Zero Order Waveplate — 12.7 mm
Tower's 12.7 mm zero-order waveplate provides a 10 mm clear aperture (85% OD) in air-spaced, laser-quality crystal quartz with a stainless steel spacer — far less sensitive to temperature variations than multiple-order plates, with no risk of the plates separating in service. Both faces are AR-coated (R < 0.25% per surface). ½ and ¼ wave standard; wavelengths within 10–20 nm of the standard list are available as a special feature.
