Technical indicators of laser pointer

The typical technical indicators of the laser pointer are related to the distance available here, and the skin damage to the human body is almost excluded. The methodology of the project can be roughly divided into several stages. Precautions for simulating actual conditions in the laboratory: In practice this result hazards mainly from the beam power and the distance of the laser pointer. The person being attacked in the (air) vehicle; this causes the irradiance to be affected by the (air) vehicle The driver's eyes. Different irradiance levels and therefore can be simulated by different-even "very large"-distances using optical elements in the optical path of the laboratory, the distance significantly shortens consciousness.
Selection of laser pointers and appropriate measurement technology During the research preparation stage, 41 different laser pointers were purchased. As a result, laser pointers from different manufacturers are mainly from the Far East, with different wavelengths and power levels selected. The wavelength of laser pointers is selected according to their distribution in the market. The selected wavelengths are 405 nm (blue), 447 nm (blue), 532 nm (green), and 655 nm (red). The specified beam power is as follows: 1 mW, 5 mW, 10 mW, 100 mW, 500 mW, 1000 mW. However, the actual measured performance varies greatly from the specified service in some cases.
Separate from the license to own a laser pointer is a question of whether it is possible to buy all grades of laser pointers in Germany. This requires a negative answer. According to Article 3 (2) of the Product Safety Law, products can only be sold on the market if they are used in an expected or foreseeable manner without endangering people's safety and health. If the danger cannot be ruled out, the product is prohibited from being sold in Germany. This applies to all laser pointers with a power higher than 1mW (hazard levels 3R ??to 4). There is a health hazard above this value. According to this, only 1 to 2M laser markers can be traded in Germany.
