LRF1222C · 1.54 µm Laser Rangefinder Module
LRF1222C accuracy and range test conditions
A range number needs a target and conditions. For the LRF1222C the published figure is Reference target(2.3m × 2.3m) ≥12 km. Accuracy: ±2 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.

FAQ
What is the maximum range of the LRF1222C?
The published range is Reference target(2.3m × 2.3m) ≥12 km. A range figure is only comparable together with the target and conditions it was measured on, so the condition is listed next to the value.
Which interface does the LRF1222C use?
The published communication interface is RS422.
What laser wavelength does the LRF1222C use?
The published wavelength is 1.54μm±0.02μm; laser safety entry: Class I stated in the module document. Final accessible-emission classification applies to the complete configuration..
How much does the LRF1222C cost?
The published single-unit price of the LRF1222C is $3,400, falling to $1,300 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
