With the continuous progress of science and technology, laser pen has been widely used in education and business demonstration, etc., because the traditional laser pen mostly uses batteries as energy, very not cover environmental protection; In addition, in the normal mode of teaching, teachers use the traditional teaching stick to guide students to analyze and teach key problems, so it is necessary to replace teaching AIDS, teachers and teachers bring inconvenience. Which hue do you prefer in the overall business presentation? Generally speaking, the most typical colors of laser caps are red, luminous blue, yellow and natural colors. Different colors produce different wavelengths. Using the wavelengths of the 473nm 300mW green laser produces the most powerful blue light, followed by the environmentally friendly 532nm and 635nm yellow. Red emits the weakest light at 650nm. The system will remind you to choose the color according to your preference. Also, if you want leds to be light, you'll have to look for Pointers with sturdy directional lights.
Laser pointer features of energy saving and environmental protection
A laser pen, including laser pen ontology, described in the green laser pointer ontology from 1, manually pull rod generator 2, the electronic module 3 and solar receiver 4, section two more armed with laser pointer for heart tube folding into a set of telescopic pole 1, electronic module 3 design inside the shell of the pen, shell made of solar panels, in-house or transformation, Push-button manual generator 2 is connected to electronic module 3. This because of the use of manual power generation and solar power supply, so can ensure to avoid sufficient electricity, and energy conservation and environmental protection, the use of dry battery waste resources, pollution of the environment defects, save the elongated can be used as the use of ordinary teaching rod, safe and convenient.
Laser Pointers that are harmless to human body
If you choose one of the environmentally friendly 300mW green high powered laser, rest assured that they are completely safe for human health. They are produced from resources based on natural resources, so they won't cause an allergic reaction or any harm to your body. Long life of light source. Compared with the traditional light source, the laser used in laser display produces single wavelength visible light without ultraviolet and infrared radiation, which avoids the disadvantage of high heat release of the traditional high-power light source. Generally speaking, it is the long service life of laser light source, as long as ten years, equivalent to the life of traditional light source ten to twenty times.
