1. Is the infrared rangefinder a laser rangefinder?
According to different principles, rangefinders can be divided into two types: ultrasonic rangefinders and photoelectric rangefinders. Among them, electric rangefinders generally use lasers for measurement, and a photoelectric rangefinder uses infrared rays for measurement. So are they the same?
Infrared rangefinder, also known as laser infrared rangefinder, is an instrument that uses modulated infrared light for precise distance measurement. It belongs to laser rangefinder. The reflection time of light is used to measure distance.
Second, what is the difference between infrared rangefinder and laser rangefinder
1. Different measurement light sources
Infrared rangefinders use infrared light as the light source for measurement, which is invisible; ordinary laser rangefinders use red light laser measurement, also known as visible light ranging, and you can see red light emitted.
2, the measurement range is different
Relatively speaking, the measurement range of infrared rangefinders is farther, because infrared rays are not diffused when they propagate, and the refractive index is very small when passing through other substances, so long-distance measurement generally uses infrared rangefinders.
3. Different measurement accuracy
Infrared rangefinders are better for long-distance measurement, but their accuracy is relatively low. Laser rangefinders, especially hand-held laser rangefinders, have relatively high accuracy.
Third, the rangefinder laser is better or infrared is better
Both laser rangefinders and infrared rangefinders use the reflection of light to measure distances, which are essentially the same rangefinders. However, there are certain differences between the two in terms of measurement range and accuracy, then laser rangefinders and infrared rangefinders. Rangefinder comparison
In fact, there is no better way to say a laser rangefinder and an infrared rangefinder. The main thing is to choose a suitable rangefinder according to actual needs. If the distance is measured, the infrared rangefinder is better; For measurement accuracy, it is more recommended to use a laser rangefinder.
