Machine vision laser diode module Z LASER Optoelektronik

Z-LASER in Machine Vision

Laser projections of dots, dot matrices, lines, multi-lines, grids, circles and other patterns in combination with miscellaneous camera types play an important role in machine vision.

For single profile measurements a camera and a laser line are sufficient. Surface contour measurements of moving objects require a camera with distortion-free or telecentric optic, a line laser and image processing tools. Dot projections are suitable for simple presence check and height measurements, crosses and target projections are in high demand in robotics, circles are used for example for weld seam checks, multi lines, grids and point matrices allow taking a height profile in one image.

The industrial image processing has very high requirements to the features of the laser line. A good homogeneity of the light intensity and an even, non-gaussian light distribution, as well as a constant line width and a high sharpness of the laser line are absolutely necessary. The image processing with projected laser structures require reliable lasers with stable wavelengths and power output. The new ZV series of Z-LASER has been systematically been developed for these requirements.
