Used for CO2 laser system combined beams mirrors
Close bunch of mirror is a kind of a semipermeable reflector, it will be two (or more) wavelength of light transmission and reflection respectively through to a optical path synthesis method. Since using znse, LiuHuaXin or germanium material and plating has optimization design film, the whole bunch of mirror reflection infrared radiation, usually transmission in the infrared visible (CO2 high power laser diode lasers used helium neon visible light path, straightening when using the combined beams mirror).

Average > 98% @ the transmission rate, the average reflectivity > 10.6 microns 650nm & 632.8 nm 85% @
