The air gap focusing mirror is used to focus the laser beam and can withstand high laser power. Its optical structure adopts a three-piece separation structure and is optimized to the diffraction limit to obtain a very small focusing spot. The use of high-quality optical lenses in the focusing mirror and the optimized design of the surface film layer for the use of wavelength can obtain a transmittance of more than 96% to 98%. Air gap focusing mirrors are commonly used in high-precision laser applications such as laser welding, laser cutting, laser drilling, and laser modeling. At the same time, it can also be used in reverse to collimate the laser emitted by the fiber to obtain a collimating laser.
