Fresnel Rhomb Retarders

Fresnel Rhomb Retarders

TECHSPEC® Fresnel Rhomb Retarders

  • Broadband Performance with <2% Retardance Variation
  • 12.7mm and 25.4mm Options Available
  • λ/4 and λ/2 Retardance Options

TECHSPEC® Fresnel Rhomb Retarders are available with design wavelengths of 532nm and 1064nm. By utilizing a specific angle, Fresnel rhomb retarders impart a retardance with each internal reflection of the light, totaling λ/4. Each design is paired with either VIS 0° or NIR II coatings to provide efficient transmission across a broad range of wavelengths. These TECHSPEC Fresnel Rhomb Retarders deliver less than 2% retardance variation across the specified wavelength range and are optimized for use in diode and fiber applications.
