The role of beam expander

2021-11-01 11:52:37

The UV laser cutting machine is an important tool in the field of micro-precision cutting. The cost of the UV laser cutting machine lies in several core components. The higher the quality of the core components, the better the stability of the UV laser cutting machine, especially the optical components, lasers and galvanometers, the three devices of the lens.

Laser lenses are the most used in the entire laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, such as all-reflection lenses, semi-reflection lenses, focusing lenses, and so on. The quality of the lens directly affects the output power of the laser, and also affects the performance of the whole machine.

Laser cutting machine beam expander has two main purposes: one is to expand the diameter of the laser beam; the other is to reduce the divergence angle of the laser beam. Therefore, it is used for long-distance illumination or projection, as well as focusing systems.
1. Make the focusing effect better and get a smaller focusing spot. The larger the multiple of the beam expander, the better the effect of focusing by the focusing lens.
2. Disperse the energy evenly, reduce the energy density reaching the vibrating lens or the reflector, and make the vibrating lens or the 45-degree reflector more durable.
3. Enlarging the beam, this is mainly reflected in the laser show system. Although we amplify the beam every time in the industrial processing system, our purpose is not only to enlarge the beam but the first two purposes, and the laser show system uses The purpose of the beam expander is to enlarge the beam.
