Buy a laser pointer
In addition to improving beam collimation, beam expanders can also be used to focus military laser beams. The spot size is in micrometers and calculated using a 632.8 nanometer red laser beam with a diameter of 0.63 mm. Assuming that the Galileo telescope design is applied to the expander laser beam, examples can be found in several Edmund Optics products, which can be used for collimation and Focus the laser beam. Any portable laser will be harmless...especially if children use these devices. High-performance red and green laser pointers are used in astronomy, and high-power green laser pointers have always been the first choice, because the average wavelength of 532nm has the most photosensitive color spectrum, even in the atmosphere at a very fast speed difference, people can still achieve the celestial bodies in the sky Brief observation.

Manufacturers usually classify their laser products as 30000mw according to international standards. According to the International Electrotechnical Commission standard 60825-1, laser products are classified into 1, 1M, 2, 2M, 3R, 3B, and 4 according to the risk level from high to low. In order to reduce the possible risks of healthy handheld lasers and battery-powered high powered laser pointers, the laser pointer should be 3R/IIIa or lower (usually no more than 5mW output power). In addition, the powerful 3000mw laser pointer is always equipped with a specially designed mounting bracket. Usually, it is unrealistic to make accurate measurements with simple square meters and triangular meters. Most of the time, users are severely limited by the precise aiming distance or height of the tools used in these manuals. However, the rifle scope laser only projects an ultra-bright, visible blue laser beam onto a target surface with high visibility and high brightness.
