Working principle and application of 905nm laser rangefinder

The 905nm Laser ranging module is a ranging device using a 905nm wavelength laser. It usually consists of a laser transmitter, a receiver, a signal processor, and a distance calculator.

The laser transmitter emits a 905nm wavelength of laser light, which is reflected by the target and received by the receiver. The signal processor processes the received signal and calculates the target distance.

The 905nm laser ranging module has the advantages of high precision, low cost and strong anti-interference ability, so it has been widely used in many fields. For example, thermal imaging, night vision and other handheld mobile device integration;

The 905nm laser is a Class 1 safety laser and is safe for the human eye, but direct exposure of the laser beam to the human eye should be avoided when used.
