The laser diode beam sources series 13LN have a fan angle between 0° and 16.8° and approx. uniform intensity distribution along the laser line. More precisely, it is Gaussian clipped by an aperture with an edge intensity of typ. 80%. Across the laser line the intensity distribution is Gaussian. The line width is constant along 60% of the central are, outside this area the line width differs up to 30%.
The lasers of series 13LN are Laser Micro Line Generators designed to produce lines with small line width. They have a small depth of focus (in this case the depth of focus is the Rayleigh range). Laser Macro Line Generators like the corresponding lasers of series 13LNM have common basic optical features but are designed to generate laser lines with an extended depth of focus.
The laser has integrated electronics for control of the laser output power. The output power can be controlled using the modulation input ports (TTL and analog) or manually using the potentiometer. Optionally the lasers can be equipped with RS232 serial interface for laser control and data read-out.
For this laser type the working distance is fixed. A fine-adjustment of the distance between laser and target is recommended for fine-focusing in order to achieve minimal line width.
