What is the difference between infrared rangefinder and laser rangefinder?

1. Different measuring light sources

Infrared rangefinder uses infrared as the light source for measurement, which is invisible; ordinary laser rangefinder uses red laser measurement, also known as visible light ranging, and red light can be seen.

2. Different measuring range

Relatively speaking, the measuring range of infrared rangefinder is farther, because infrared does not diffuse when propagating, and the refractive index is very small when passing through other substances, so long-distance measurement generally uses infrared rangefinder.

3. Different measuring accuracy

Infrared rangefinder is better for long-distance measurement, but its accuracy is relatively lower. Laser rangefinder, especially handheld laser rangefinder, has a higher accuracy.

Which rangefinder is better, laser or infrared?

Both laser rangefinder and infrared rangefinder use light reflection to measure distance. They are essentially the same rangefinder, but there are certain differences in the measuring range and accuracy between the two. So which one is better, laser rangefinder or infrared rangefinder?

In fact, there is no saying that the laser rangefinder and the infrared rangefinder are better. The main thing is to choose the appropriate rangefinder according to the actual needs. If you want to measure long distances, the infrared rangefinder is better; if higher measurement accuracy is required, it is recommended to use a laser rangefinder.
