The laser diode beam sources series LNC-13LT/LNC-13LTM produce semi-telecentric laser lines with a uniform intensity distribution along the laser line.
The laser diode beam sources series LNC-13LT/LNC-13LTM produce a semi-telecentric laser line with 15 mm line length. The intensity profile is approx. uniform in line direction. More precisely, it is Gaussian clipped by an aperture with an edge intensity of typ. 80%. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian for lasers of series LNC-13LT and approx. Gaussian for lasers of series LNC-13LTM.
Micro and Macro lasers
The lasers of series LNC-13LT 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 LNC-13LTM have common basic optical features but are designed to generate laser lines with an extended depth of focus.
The lasers are low noise (typ. < 0.15 % of Po* (RMS, Bandwidth < 1 MHz)) and operate mode-hopping free. Due to the reduced coherence length the speckle contrast is lowered. However this effect is smaller for smaller lines. (* Po is the maximum specified output power.)
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.
Adjusting the working distance
For lasers of series LNC-13LT/LNC-13LTM 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.
The laser series LNC-13LT/LNC-13LTM is also available as a standard version 13LT (Micro) and 13LTM (Macro). Please note that these have a different electronics type, but are also available with RS232 interface.
These high quality lasers can e.g. be used for machine vision applications, laser triangulation or laser light sectioning.
