Fiber Laser Marking Machine Field Lens

The main technical parameters of the field mirror are: working wavelength, incident pupil, scanning range and focused spot diameter.

Working wavelength: mainly depends on the wavelength of the laser. The lens of the field mirror is coated at a given laser wavelength. If the field mirror is not used within the given wavelength range, the field mirror may be burned by the laser or the required laser transmittance is very low.

The laser field lens focuses the beam to produce a high-energy-density focus to process the working material, and combines it with a galvanometer that quickly and accurately changes the direction of the laser beam to realize high-speed precision processing and processing of materials.
