The ONG300 multifunctional ranging telescope emits an invisible and harmless infrared pulse by aiming at an object, and then calculates the accurate distance of the target by continuously measuring the time of the pulse back and forth. Laser distance measurement mainly depends on the degree of reflection with the target object, and generally traffic signs have good effects. Because the color, surface treatment level, size, and shape of the target will directly affect the reflectivity of the object, thereby affecting the distance of distance measurement.

It has a simple and lightweight design and is widely used in industrial inspections, power sector measurements, and railway surveying industries. Outdoor sports surveying such as golf, hunting, building surveying and design, fire protection systems, etc.

The impact of different reflectivity targets on ranging capability is significant. The distance of this series of laser ranging telescopes is defined according to the following conditions:

1. Reflectors have moderate reflectivity, such as building walls

2. The surface of the reflector is perpendicular to the direction of laser emission

3. Measure the weather conditions as clear but not in direct sunlight.

4. The area of the reflector shall not be less than 2m * 2m
