A laser rangefinder is an instrument that uses a laser to accurately measure the distance to a target. The laser rangefinder emits a very fine laser beam to the target during operation. The photoelectric element receives the reflected laser beam from the target. The timer measures the time from the laser beam emission to the receiving and calculates the distance from the observer to the target.
If the laser is continuously fired, the measuring range can be up to about 40 kilometers, and the operation can be performed day and night. If the laser is pulsed, the absolute accuracy is generally low, but for long distance measurements, good relative accuracy can be achieved.
The first laser in the world was first developed by the United States Hughes Aircraft Company's Meyman in 1960. The US military soon carried out research on military laser devices based on this. In 1961, the first military laser range finder passed the US military demonstration test, after which the laser rangefinder quickly entered the utility consortium.
The laser rangefinder is lightweight, small in size and easy to operate. The error is only one-fifth to one-hundredth of that of other optical distance meters. It is widely used in topographic measurement, battlefield measurement, and tanks. Targets are measured by aircraft, ships, and artillery, and the heights of clouds, aircraft, missiles, and artificial satellites are measured. It is an important technical equipment to improve the accuracy of high tanks, aircrafts, ships and artillery.
As the price of laser rangefinders continues to decrease, the industry has gradually begun to use laser rangefinders. At home and abroad, a number of new miniature distance meters with fast ranging, small size, and reliable performance have emerged, which can be widely used in industrial measurement and control, mining, ports and other fields.

CNC mills use multiple rotary cutting tools to create different effects and to remove different degrees of excess material. Some of the most commonly used CNC tools include:
- Routers. These multi-purpose tools provide multiple functions. They can act as bores, panel saws, spindle molders, and cutters.
- Grinders. When materials need to be finished to a certain degree of smoothness, grinders can abrade the substrate until it meets the required conditions. Grinders can finish specialty tools, medical implants, and other instruments.
- Tool setter. These parts manage the CNC milling tools. They ensure the tools set into the spindle at the desired length and can detect wear or breakage
