Harmonic Separator Mirror for Nd:YAG lasers (HHS)

  • Separates fundamental from harmonic wavelengths
  • High power application

Harmonic separators are used to reflect the wavelength of interest while allowing others to pass. They have anti-reflection coatings on the rear surface. Reflectance is at least 99.5% for the wavelength of interest and transmittance is in excess of 90% for the rejected wavelength (85% in the case of 532 nm).
