Laser Modules with Beam Shaping Optics

Laser Line, Micro Focus, Laser Pattern Generators

Laser line generators, laser micro-focus and pattern generators are, e.g., used for 3D measurement tasks, using laser triangulation or laser light-sectioning techniques. All models come ready to use with an internal electronics.

Physics Fundamentals: Laser Diodes and Collimation

Physical basics and information concerning:

  • Laser Diodes and collimation
  • Depth of focus of laser lines and laser spots
  • Line width and spot size for determinations
    • Micro focus and micro line
    • Macro focus and macro line
  • Laser Speckle and its influence on the signal
  • extrapolation of line lengths and line widths

Laser diode collimator transfer the divergent light of a laser diode in a collimated beam. The gaussian intensity distribution and the elliptical intensity profile is maintained. With the two emission angles θ and θ|| of the laser diode and the focal length of the collimation optics, the orthogonal and parallel divergence angles and beam diameters can be determined. These values depend on the laser diode used for the collimation.
