LR1200D23 · 905 nm Laser Rangefinder Module
LR1200D23 accuracy and range test conditions
A range number needs a target and conditions. For the LR1200D23 the published figure is 4 m – 1,200 m (max. 1,200 m) (Target reflectivity, target dimensions and atmospheric test conditions are not stated in the reviewed public technical table; confirm the applicable controlled document.). Accuracy: δ ≤ ±1 m, 4 m ≤ d < 1000 m¹) (Standard version: ±1 m).

How to read the conditions
Reflectivity is the fraction of laser light the target returns: a white board is about 90 percent, a building about 70 percent, grass and soil 10–30 percent. Visibility limits long-range figures because haze absorbs the pulse both ways. When two modules quote different targets, convert both to the same target before comparing; the open module database lists every vendor's condition next to its number.
