The color and brightness of the light are different. The color of the most powerful scanner depends on its working speed and the wavelength of the magnifying glass. The contrast of green light, red light and bright red light is poor: green light > red light > blue light < blue purple light. The price is red light < green Sequin > blue laser heat source absorption (trigger): green light < Red > blue purple > blue light. Stability: green light < Red > > blue violet light < < under the tone of X-ray pen, if there is blue light to protect our eyes, we can effectively protect our eyes. In order to protect the eyes from damage, the balance of pigment cells in the retina must be sensitive. The light of most powerful laser pointer color can be seen separately under the irradiation of the light entering the retina, resulting in color blind spots and dark differences on the retina. Plus color blindness.
This powerful laser pointer color has very powerful characteristics. In addition to the Laser pointer, it can also be used for teaching, field research and astronomical positioning. It's a long time and convenient. There are many encryption methods on the market, which can be classified according to function and wireless broadcasting technology. When you play slides on the screen, we will make some marks, usually red marks. Can't you change it? Of course not. Taking the slides of 2013 as an example, this paper compares the laser line paint and pigment with the PPT of 2013. After the optical principle, the brightness of the cold color is very high, so that the blue laser Stift Heller. In fact, choosing green or red taschensample laserlicht Lichtquelle can be based on personal preferences, but if needed, because it is the most obvious effect of green for a long time, RGB laserlichtquelle.
