  • These Nd: YAG/YLF laser mirrors are designed for high reflectance at the appropriate dual wavelengths. They are intended for external use at either 45° or normal incidence. We also offer dual wavelength mirrors for use at the fundamental and second harmonic wavelengths as well as a selection which will reflect a Hene or diode laser guide beam as well as the fundamental wavelength.
