The low noise laser diode beam sources series LNC-13LN/LNC-13LNM produces laser lines with a small 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 for the series LNC-13LN and approx. Gaussian for the series LNC-13LNM. For series LNC-13LN the line width is constant along 60% of the central area, outside this area the line width differs up to 30%.
Micro and Macro lasers
The lasers of series LNC-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 LNC-13LNM 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-13LN/LNC-13LNM 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-13LN/LNC-13LNM is also available as a standard version 13LN (Micro) and 13LNM (Macro). Please note that these differ in 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.
