Product Family Description

  • Damage Threshold up to >20 J/cm2 @ 1064nm
  • λ/4 and λ/2 Retardance
  • Black Anodized Aluminum Mount
  • UV to NIR Design Wavelengths Available

High Energy Quartz Waveplates are available in both λ/4 and λ/2 retardance for discrete laser wavelengths from the UV to NIR and can withstand energy densities up to >20 J/cm2 at 1064nm. A large acceptance angle and wide operating temperature range enables these waveplates to be integrated into harsh environments applications. High Energy Quartz Waveplates are mounted in a black anodized aluminum housing for easy identification and system integration.
