Laser Marking Machine Lens Diameter Size Difference Field Mirror: also known as flat field focusing mirror, scanning lens, F-theta mirror. Mainly used to focus the light out of the galvanometer in a plane, fiber optic marking machine and semiconductor marking machine wavelength is 1064nm, the two field mirror is generally can be common.
But sometimes if you use the original imported scanlab scanner, it may not be M85 * 1 field mirror connecting ring, and the field mirror is generally M85 * 1 thread, this time we need to use a field mirror adapter ring.
As you know, the laser energy attenuation in the air is very strong, then that is to say, ? The larger the focal length of the field lens, the greater the laser energy loss, then the thicker the lines played out, and the shallower, so the amplitude of the field mirror must be selected to choose the most appropriate on the line, do not blindly seek large.
