The laser pointer can effectively drive off the annoying crows
In addition, the laser pointer crow attached to the telescope is also very suitable. If the distance to the telescope is relatively limited, the laser pointer power can easily help the telescope to quickly and clearly aim at an object with a powerful beam. You can operate the blue laser pointer in every corner. Class I: Low-power high power laser pointer (power less than 0.4mW), regardless of whether the eyes and skin do not exceed the MPE value, even if the optical system is used to focus, it does not exceed the MPE value. Can you provide construction safety without special control? General applications such as the strongest laser pointer, CD player, CD-ROM equipment, geological exploration equipment, laboratory analysis, etc. In astronomical research, people usually have to point, wave their arms, scream loudly, point to celestial bodies and explain a lot . In this case, it is always difficult for teachers and teachers to tell which celestial body they are referring to. Therefore, the visible super bright green laser pointer is an excellent alternative to traditional pointing tools such as sticks and fingers. Coherent Corporation and Spectrophysics Corporation are the two largest laser companies in the United States, accounting for more than 40% of the total sales of American Laser Corporation. The high-power CO2 laser equity of the Industrial Laser Division of Spectrophysics has been acquired by the German Rofin-Sinar company, which mainly produces 1.5kW-6kW cross-flow CO2 lasers.

Be careful when using tuned lasers to observe celestial bodies. Pointing the laser pointer at the aircraft can cause serious damage. In any case, as long as you are careful, you can spend a good time in your astronomy research career. Class II: Visible laser low power (power 0.4mW-1mW), closed eyes response time 0.25 seconds. Use this time to calculate the exposure value. You cannot exceed the error limit. The green laser pointer acts as a microphone. Lasers less than 1 mW usually cause dizziness, but not. It is not completely safe to close your eyes and protect your eyes. Be careful when directly entering the beam. Others are lasers to avoid observation of protection class II. Typical applications include classroom presentations, 5mW laser pointers, sights, rangefinders, etc. United Technology Corporation mainly produces 5kW-30kW high-power cross-flow CO2 lasers, and has a joint venture with a German company to manufacture such equipment in Germany; PRC mainly produces 0.5-3.5kW axial fast-flow CO2 lasers, and has sold 1,000 high-power lasers. CO2 laser; Combustion Engineering Company produces 1kW, 5kW and 10kW high-power cross-flow CO2 lasers (patent of Israel MLI company).
