Our 940nm 500W super light stick--We have a genuine 940nm super light device, high efficiency 100W. This article is a very light naked article, which is a medical and scientific research ideal choice, and it is not suitable for practical use, and can be used at any time. Understand the product's accuracy and efficiency. Under ideal conditions, diode strips can last for thousands of hours. However, devices often fail long before they reach the specified service life. Water cooling is usually quite effective, but its effectiveness may be greatly reduced by corrosion, which occurs, for example, when the chemical conditions of the cooling water (especially the ionic content) do not meet specifications. On the other hand, excessive cooling can lead to condensation problems when the dew point is reached. In addition, deviations from the intended operating temperature can lead to significant deviations in the emitted wavelength, typically with a temperature coefficient of about 0.3 nm/K. Obviously, the entire diode laser system has to be properly engineered in order to realize the full lifetime potential of the bar laser.
