Our company as a professional manufacturer knows this product very well.
Let's introduce some professional terminology to you.
ACCURACY: The tolerance of the laser beam at a certain distance from the tool. This indicates how far the beam may deviate from 'perfect' measurement.
ABSORB: To transform radiant energy into a different form, usually with a resultant rise in temperature.
AUTOCOLLIMATOR: A single instrument combining the functions of a telescope and a collimator to detect small angular displacements of a mirror by means of its own collimated light.
CALIBRATION:A procedure for bringing the accuracy of the laser to within it's factory specifications.
LASER:A device that produces an intense, coherent, directional beam of light by stimulating electronic or molecular transitions to lower energy levels; an acronym for Light Amplification by Stimulated Emission of Radiation.
AMPLITUDE :The maximum value of the electro-magnetic wave, measured from the mean to the extreme; simply stated: the height of the wave.
Ultrashort Pulsed Laser:Laser whose pulse duration time is very short, below 1 ns, usually in the fs scale.
