• 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.
