Laser lines and laser spots are used for a large variety of applications. Depending on the required depth of focus of the laser line, either micro lines with a high power density and smaller depth of focus or macro lines with increased depth of focus are appropriate. Special variants with low noise and reduced coherence can improve the measurement results.
