-Main features-

  1. We use different lasers due to a wide range of applications. For example, the use of blue lasers instead of red ones is optimal for the control of shiny materials, high temperature objects and organic materials. The use of scanners with lasers of different wavelengths in one measurement system makes it possible to avoid the scanners mutual influence and greatly simplifies the system construction. Scanners with power IR laser are intended for use in conditions of large solar radiation.

  2. Scanners can be equipped with a built-in heater for operation under low temperature conditions. Scanners can be equipped with a air (water) cooling system and air-knife system for windows. 

  3. In addition, you can use the ROI function, which makes it possible to increase the working frequency of the scanner in the limited working range up to 20000 Hz.

-Measuring principle-

Operation of the scanners is based on the principle of optical triangulation.

Radiation of a semiconductor laser is formed by a lens in a line and projected to an object. Radiation scattered from the object is collected by the lens and directed to a two-dimensional CMOS image sensor. The image of object outline thus formed is analyzed by a signal processor, which calculates the distance to the object (Z-coordinate) for each point of the set along the laser line on the object (X-coordinate). Scanners are characterized by base distance (beginning of the range), SMR, for Z-coordinate, measuring range (MR) for Z-coordinate, measuring range for X-coordinate at the beginning of Z (Xsmr) and measuring range for X-coordinate at the end of Z (Xemr).
