Why is high power uv laser so expensive?

The fiber laser printers and carbon dioxide laser printers on the market are cheap, have a long service life, are easy to maintain, and have low environmental requirements. So why are UV laser printers so expensive? In contrast, shorter service life and more careful maintenance? Today's RFH laser editor will introduce to you the reasons for the high price of UV laser inkjet printers.

Why are UV laser printers expensive?

The structure of the UV laser printer is the same as that of the fiber laser printer. and other original components. So how many times the price of the UV laser printer is that of the fiber laser printer?

The optics of fiber laser printers and UV laser printers cannot be used in common. The wavelength of the UV laser is 355nm, and the wavelength of the fiber laser is 1064nm. The wavelength of the ultraviolet laser is the wavelength after frequency doubling on the basis of the wavelength of 1064nm. The technical difficulty is greater, resulting in the price of ultraviolet lasers several times that of fiber lasers;

Compared with the fiber laser printer, the thickness and material of the galvanometer and lens of the UV laser printer are different, so they cannot be used universally, and the galvanometer and lens of the UV laser printer are also more expensive. Of course, the prices of conventional galvanometers and lenses on the market are not much different, and the main price difference is in UV lasers and fiber lasers.

On the other hand, UV laser printers have relatively high requirements on the environment, especially water-cooled lasers, which need to maintain a constant temperature, so the requirements for accessories are relatively high. Due to the small focusing spot and the small processing heat affected zone, the UV laser can perform ultra-fine marking and special material marking. It is the primary choice for customers who have high requirements for marking effects. In addition to copper materials, UV lasers are more suitable for processing. Not only the beam quality is good, the focusing spot is small, and ultra-fine marking can be realized; the scope of application is wider; the heat-affected area is small, no heat effect, and no material burning problem.

In general, the price of UV laser printers is relatively high, which is mainly reflected in the high cost of UV lasers and high labor costs in the later period.

So the UV laser printer is very expensive, what is the current price? It mainly depends on the price fluctuation of UV laser manufacturers. For example, in the early years, there were no ultraviolet laser manufacturers in China, and 3w imported ultraviolet lasers also required hundreds of thousands. With the breakthrough of domestic technical barriers, the price of 3w UV lasers has also dropped significantly. So far, pure imported top UV lasers only cost tens of thousands of RMB. Therefore, the price trend of UV laser printers depends on the overall development of domestic UV laser manufacturers and the development of market applications.
