6.1  Factors affecting the measurement range

 

Laser  distance  sensor  is  a  new  of  non-contact  optical  measuring  equipment.  Its 
measuring  range  and  accuracy  will  be  effect  by  many  external  environmental 
factors. So actual measuring result might be different with typical value which is 
measured in standard environment. 
The following factors will effect actual measuring range: 

Effect Factors 

Increase measuring range 

Decrease measuring range 

Surface of 

target 

Bright and smooth surface with 

good reflection, like target plate 

Deep color and rough surface, 

like green or blue target surface 

Air visibility 

Clean air 

Dust, fog, storm and rain, snow 

Ambient light 

Dark environment 

Target exposure to strong light, 

like sunlight in midday 

Laser emission 

Laser emission lens and 

protection glass keep clean and 

smooth 

Laser emission lens and 

protection glass get dirty or 

scratched 

In conclusion, the best measuring result will be happen in a dark environment 
and with a good reflection target. We strongly suggest to use a target plate when 
laser distance sensor works in a poor environment. 
We also suggest to keep laser emission lens and protection glass clean with a soft 
cloth before start to using.
