Dichroic Mirrors

  • Laser Damage Threshold: >2J/cm2, 8 ns pulse, 1064 nm typical for BK7 substrates; >5J/cm2 8 ns pulse, 1064 nm typical for UVFS substrates
  • Back side antireflection coated: R<0.5%
  • Parallelism: 30 arcsec

Harmonic separators are dichroic beamsplitters used to reflect one wavelength and to transmit the others. Reflectance of >99.5% for the wavelength of interest and transmittance of >90% for the rejected wavelengths. The rear surface of harmonic separators is antireflection coated.
We also suggest to take a look at our SALE items – non standard dichroic mirrors that are available ex-stock.
