LAP laser of PY series with green beam are used, where visibility of red laser lines is not sufficient.

This can be depending on surface (e.g. red or black, wet stone) or light conditions (e.g. bright sunlight). Green light has a visibility about five times higher compared to red light, because human eyes have their maximum sensitivity in this wavelength area.
The laser beam is collimated for optimum line width in working distance. The new SUPERLINE optic allows to set the line width manually and to position the center of the brightness distribution along the laser line.

The robust housing made of coated aluminium protects laser, electronic circuitry and precision optics. The Peltier-Cooler, marked by the black fins, takes care of the right working temperature and prolongs life expectancy. Temperature is tracked internally, and the laser is swiched off in case of high temperatures to protect the laser source from damage.
