Introduction

Laser systems are used where detection of small objects or precise positioning is required. They are available as through-beam sensors, retro-reflective sensors or diffuse reflection sensors.

Laser light consists of light waves of identical length which have a defined phase relation (coherence). This results in an important feature of laser systems, that is the almost parallel light beam. Result: Due to the small angle of divergence long ranges of up to 60 metres can be achieved. The laser spot which is also clearly visible at daylight simplifies the alignment of the system. Apart from the advantages some points have to be taken into account for the selection of the suitable optical system: compared to standard sensors the laser sensors have a reduced temperature range (-10...50 °C). In view of the small light spot and the often high ranges the system is more sensitive to vibrations than standard sensors.

Mounting aids

The ifm laser sensors offer a useful function for easier alignment: The laser power is increased during adjustment: This leads to a particularly bright laser spot which enables industrial safe alignment from a distance even at daylight.

How dangerous are laser sensors?

Due to the small angle of divergence laser beams are focussed on a small area. The energy and power density on this area is extremely high. ifm laser sensors comply with the European standard EN60825 or the international standard IEC60825. These standards describe the operation of laser systems.

ifm laser sensors are classified in the laser protection class II. Thus the laser power, also in the setting mode with increased power, is max. 1 mW. When the laser beam hits the human eye, the eyelid is instinctively closed. When hitting the unprotected eye within a time of 0.25 s the laser beam must not cause any damage.

Coherent: Laser sensors emit light of a defined wave length and the same phase position.
