Dual-wavelength waveplate #3835

Product Description
TECHSPEC Fresnel Rhomb Retarders are designed for 532 nm and 1064 nm operation. Using a precise internal angle, each internal reflection produces part of the retardance so that the cumulative effect yields a total λ/4 retardance. Each design is available with VIS 0° or NIR II coatings to ensure efficient transmission across the target wavelength band. These retarders exhibit less than 2% retardance variation over the specified bandwidth and are optimized for diode and fiber-based laser applications.
