◦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.
