Products: Dual-Wavelength Laser Mirrors

Dual-Wavelength Laser Mirrors image

Specially designed multilayer dielectric coatings, electron beam deposited onto laser-grade substrates, enable maximum reflectance of high-energy excimer and UV laser wavelengths plus >50% reflectance at a specific visible laser wavelength from the same mirror.  

Standard mirrors are designed as Nd:YAG laser harmonic and excimer/HeNe laser reflectors. These mirrors permit dual-wavelength reflection for laser harmonic generation and excimer alignment applications. Acton has standard 45° mirrors for 248nm, 308nm, and 353nm excimer wavelengths, as well as 266 nm (as listed below).

Note: Other UV and visible laser wavelengths and angles of incidence are available on request. Contact us at [email protected] for more details.
