Understanding Rangefinder Accuracy Specs: ±m vs %
Why every accuracy line on our spec sheets has two parts — a fixed near-range figure and a distance-proportional term — and how to read it correctly for the distance band your system actually operates in.

How 905 nm DToF Laser Ranging Works
Inside the pulse-out, photon-back measurement loop that turns a 905 nm laser diode and an avalanche photodiode into a distance reading — and why the numbers on our spec sheets (frequency, valid measurement rate, false alarm rate) describe that loop, not just a laser.
