1. Laser
rangefinders are divided into three categories, one is handheld laser rangefinders, this type of rangefinder has a relatively short measurement distance, generally 20--250 meters, and has high measurement accuracy, generally 1-2 mm. very broad.
2. Telescope laser rangefinder. This type of laser rangefinder has a long measurement distance, generally 500-2000 meters, and its accuracy is relatively low. The general accuracy is 0.5-1 meter. The main application scope is long-distance field measurement, such as electricity, Environmental protection, forestry, animal and plant protection, field trips, etc.
3. The laser ranging sensor has high precision requirements and can be integrated with other equipment. It is mainly used in industry, online monitoring, etc.
The first type of handheld laser rangefinder is mainly used for high-precision interior design measurement, with high measurement accuracy of about 1mm, and the measurement distance is generally from 40-250 meters. This is currently the most widely used laser range finder.
The handheld laser range finder can be divided into two types: indoor type and outdoor type. The range of the outdoor type is 200-300 meters. (The instrument itself has a built-in camera and a telescope aiming amplifier. Within a range of 70 meters, no reflector is required for outdoor use in sunlight; if the range exceeds 70 meters in the sun, please use it in conjunction with a reflector). The difference between it and the indoor type is that the hand-held laser range finder used in the indoor type has a short range of 40-100 meters. Because there is no built-in magnifying sight, it can only be used indoors (outdoor sunlight is strong, and the laser spot smaller than a cigarette end is difficult to see).
