Laser micro focus generators of type 5M+25CM generate elliptical and Gaussian laser spots. All have integrated electronics and can be modulated externally. The beam-shaping optics define the optimum working distance and the focussing range; the chosen laser module defines the wavelength and power output and, thereby, the laser safety class.
The spot diameters listed in tables below are valid for the nominal working distance of the micro or macro focus optics. Any working distance changes do require refocussing within the available focussing range, with the spot size increasing in direct proportion with greater working distance.
