Dual-wavelength waveplate #4522

zero order

Overview
DUV vacuum-compatible waveplates are mounted in an unanodized aluminum housing and feature adhesive-free construction to minimize outgassing in vacuum environments. They are optimized for >99.8% transmission at the designed wavelengths of 257 nm or 266 nm. Available retardance options include λ/2 (half-wave) and λ/4 (quarter-wave). Constructed as zero-order waveplates to provide superior retardation tolerance, increased bandwidth and reduced temperature sensitivity. The fast axis is marked on the mount edge for easy identification and system integration. These waveplates are suitable for life-science and lithography applications that require vacuum conditions.
