Harmonic Separators
They are made of all multilayer-coated with dielectrics of different refractive index by high precision substrate. Actually They are used to separate the various harmonic components of frequency doubled laser systems by selective spectral reflection and transmission. They reflect specific wavelength beam and transmit other wavelength when the angle of incident is 45 degree or 0 degree. They are often useful for YAG laser system
