Beam Combiners

Beam combiners are partial reflectors that combine two or more wavelengths of light -- one in transmission and one in reflection -- onto a single beam path. Commonly ZnSe, ZnS, or Ge, beam combiners are optimally coated to transmit infrared light and reflect visible light, as in combining infrared CO2 high-power laser beams and HeNe visible diode laser alignment beams.
