Operating principle
The distance is determined along a laser beam emitted measurement until impinges on a reflective surface.
Thanks to laser measurement point is perfectly identifies the measurement objective. The range depends on the reflectivity
and the quality of the lens surface measurement.
Measuring rough surface
In measurements on a rough surface an average value, resulting in a higher value for the center of that area peripheral laser
beam it is measured.
Measurement on curved surfaces or inclined
If that point obliquely to these surfaces, in certain circumstances the tool could receive insufficient light energy or, if pointed at
right angles, too much light energy.
Measurement in wet or shiny surfaces
Whenever the laser meter can point on the surface, it can be measured reliably distance to the target.
When it comes to highly reflective surfaces there must be a limited scope or measurements to the reflection of light.
