Tower's 10mm Zero Order waveplates provide users with high performance Crystal Quartz waveplates that have a clear aperture of 8mm. These waveplates are air spaced, having an air space between two crystal quartz plates that form the zero order capability. Zero order waveplates are far less sensitive to temperature variations while the air spaced construction provides higher thermal stability and power handling capability. As such, there are no failures as occur with contacted waveplates which may come apart. Angular alignment of the two plates is also more accurate.

These 10mm waveplates are made from laser quality crystal quartz and each plate is anti-reflection, AR, coated on both sides. Standard retardations are ½ and ¼ wave. The waveplates are offered unmounted with a diameter of 10mm or mounted in a 12.7mm or 25.4mm anodized Aluminum mounting ring, both with a clear aperture of 8mm.

There are 49 standard wavelengths, ranging from 248nm to 2020nm, to choose from for multiple order waveplates. These same wavelengths are available for zero order waveplates but, in addition, Tower can supply any wavelength which is in the range of ±20nm of any of the standard 49 wavelengths.
