Harmonic separators are designed to separate specific YAG harmonics from other harmonics. We offer three standard wavelength (1064nm, 532nm, 355nm) reflectance YAG harmonics.

◦These mirrors are coated with multi-layered dielectric with different refractive index, using BK7 optical parallels with λ/10 surface flatness and parallelism of 5 arc second. The other surface is coated with multi-layer anti-reflection.
◦These mirrors are used at 45° incident angle to reflect specific wavelength beam and transmits other YAG wavelengths.
◦For plate type, you can use a large laser beam diameter.

▶For a guarantee in reflected wavefront error or transmitted wavefront error, please contact our Sales Division with your requests.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶The reflection surface is indicated with an arrow on the side of substrate.
▶The reflectance curves are based on actual measurements and may vary from different manufacturing lots.
▶Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
▶The reflectance in the specifications list is at random polarization or (p-polarization reflectance + s-polarization reflectance) / 2.
