Low Noise Macro Line Generator with a fan angle


Laser line with a fan angle, approx. uniform intensity distribution and extended depth of focus.
  • Line length: 150 mm
  • Line width: 66 µm
  • Wavelength: 640 nm
  • Working distance: 483 mm
  • Depth of focus: 14.6 mm
  • Low noise laser module (0.1 % RMS, @<1 MHz)
  • Macro Line Generator for extended depth of focus
  • Low noise, low coherence laser module (typ. < 0.15 % of Po (RMS, Bandwidth < 1 MHz))


The laser diode beam source type LNC-13LNM40-S500-7+91CR-640-5-H22-M60-H-6 has a fan angle of 15.8°, approx. uniform intensity distribution along the laser line and extended depth of focus.

More precisely, it is Gaussian clipped by an aperture with an edge intensity of 74 %. Across the laser line the intensity distribution is Gaussian.

The laser has integrated electronics type H for control of the laser output power. It is a low noise laser source (0.1 % RMS,@<1 MHz) with reduced coherence length and operates mode-hopping free. Due to the reduced coherence length the speckle contrast might be lowered. Please note that this effect is smaller for smaller lines and spots. The output power can be controlled using the modulation input ports (TTL and analog) or manually using the potentiometer.

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.
