The high-speed galvo scanning technology will be adopted for green laser pointer

The laser is the 20th century, after the following atomic energy, computers, semiconductors, the human is another major invention. Its principle as early as in 1916, the famous physicist Albert Einstein found until 1958, but the laser was only the first successful manufacturing. Laser came into being in the context of theoretical preparation and production practice, an urgent need for one to come out, it won the unusually rapid development, the development of the laser not only the old optical science and optical technology gained a new life, but also lead to throughout an emerging industry. Laser enable people to effectively use advanced methods and means unprecedented, unprecedented effectiveness and results, thus contributing to the development of productive forces. green laser pointer can be applied in the X-ray film teaching.
The biggest advantage of the infrared laser applications in the lighting field has a very high luminous efficiency and luminous intensity laser, semiconductor laser, electro-optical conversion efficiency of up to 80%, greatly reducing energy consumption, increased lighting, distance, and due to the laser control technology specificity makes the life of the laser product is guaranteed. The difference of the laser illumination and LED lights. Lighting distance: a single LED optical output power is generally 5 ~ 15mW, and now there are 40 ~ 50mW LED products come out, but still can not tube and semiconductor laser (LD) compared to the luminous power of the semiconductor laser in single-core tube up to 10W, the brightness of a laser tube is equal to the sum of hundreds of LED brightness. The high-speed galvo scanning technology will be adopted for green laser pointer.
Therefore, a relatively small laser products can reach a great distance from the radiation, greatly improve the radiation effect, to improve clarity. Volume: infrared laser illuminator with a single chip semiconductor laser tube as the light-emitting medium, so the volume can be small, at the same time to meet the requirements of the brightness. Life: the semiconductor laser tube and the LED is a semiconductor light-emitting products, semiconductor products for the life of a large extent subject to the handling of the product heat. Laser illumination due to the metal package and a dedicated power supply, temperature control through advanced semiconductor technology, to achieve the perfect temperature control products always set a reasonable temperature, life can well be assured. LED products, LED tube filling plastic packaging and LED lamps require assembly, so the heat capacity. green laser pointer can make the demonstrators feel easy.
And this heat directly affect the life of the product, making LED products in use for some time after the light fades, a direct impact on the effect of product use, and even product obsolescence. Red exposure effects: near-infrared semiconductor light-emitting products red exposure problem, which is determined by the semiconductor light-emitting mechanism. However, the presence of luminous infrared laser illuminator uses a single chip, making the red exposed only a small luminous point can be ignored, even in the long-distance lighting. LED lights are assembled by a number of LED tube, red exposure cause the product to the entire panel of the red exposure, which is not conducive to covert infrared light. green laser pointer will be your best partner.
(5) Cost: semiconductor laser tube and the LED mode of production is very similar to the core chip through epitaxial growth to achieve, and then through a variety of packaging technology to meet the work requirements of the chip. The difference in costs is mainly due to the amount of production, the LED package is simple, a huge amount of applications, so it can be a large-scale production, thus greatly reducing the cost of the product; With the continuous development of the application of laser technology, semiconductor laser tube production the years into a geometrically increase the costs of products has been reduced to a stage that can withstand the ordinary user, and cost reduction is still the ultimate cost of production of the laser tube can reach the current level of the LED. This kind of green laser pointer is the smallest green light pen.
