CO2 Laser Beam Combiner 20mm 25mm Dia

This is a beam combiner that allows a 10600nm beam (CO2 laser) to pass through it like a lens. It reflects other wavelength light beams, for example, the red laser pointer with visible light, which likes a mirror. It's ideal to add a "red dot" to target a CO2 laser machine so it's without the hassle of adding a red laser pointer to the laser head.
