780nm, Quarter Wave, Air Spaced Zero Order Waveplate of Quartz, Mouted Dia 25.4mm, Code 2085-009.
Hangzhou Shalom EO offers zero order half waveplates, zero order quarter wave plates, and zero order octadic waveplates, the modules with air gap design have particularly promoted damage threshold and are suitable for high energy lasers. Air spaced zero order waveplates made from single crystal quartz are available in both stocked and customized versions, with optional wavelength range from 200nm to 2000nm. Besides, Shalom EO also provides zero order waveplates made from Magnesium Fluoride (MgF2) in various design forms (air spaced, optically contacted or NOA61 cemented), with a wider optional wavelength range from 190nm to 7000nm (p.s. MgF2 zero order waveplates only accessible in customized versions, please contact our tech support if you are interested).
