Description

The laser diode beam sources series 5LM/5LMM and 5LP/5LPM produce laser lines with a fan angle and Gaussian intensity distribution along the laser line. 

5LM vs. 5LP
The laser diode beam source series 5LM produces laser lines with a smaller fan angle of 8° or 15°. The intensity profile is Gaussian in line direction clipped by an aperture with an edge intensity of typ. 30%. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian for the Series 5LM and approx. Gaussian for the series 5LMM. 

The laser diode beam source series 5LP produces laser lines with a large fan angle of about 40°, 62°, or 84°. The intensity profile is Gaussian in line direction clipped by an aperture with an edge intensity of typ. 30%. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian for the series 5LP and approx. Gaussian for the series 5LPM.

Micro and Macro lasers
The lasers of series 5LM and 5LP  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 5LMM and 5LPM have common basic optical features but are designed to generate laser lines with an extended depth of focus.

Electronics
The lasers have 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. Please note that the compact version (more details below) has different electronic features.

Adjusting the working distance
For lasers of series 5LM and 5LP 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.

Optional: Low Noise Version
The laser series 5LM/5LMM as well as 5LP/5LPM are also available as a Low Noise versions LNC-5LM (Micro), LNC-5LMM (Macro), LNC-5LP (Micro) and LNC-5LPM (Macro) . These 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.)

Compact Version
The laser series 5LM/5LMM as well as 5LP/5LPM are also available as a compact version 5LM+25CM (Micro), 5LMM+25CM (Macro), 5LP+25CM (Micro) and 5LPM+25CM (Macro). Please note that these differ in electronics type and are not available with RS232 interface or as a Low Noise LNC version.

These high quality lasers can e.g. be used for machine vision applications, laser triangulation or laser light sectioning.
