460nm blue light laser pointer option
The 460nm blue laser can be optionally equipped with a finished laser diode, which can maintain stable performance in various working environments. Equipped with an internal compact circuit board and metal heat sink cooling system, this blue laser can be used in a variety of fields of operation even in quiet conditions. The battery-operated blue green laser pointer provides a long battery life of 180 minutes at a time. The style of the green laser pointer can always bring a lot of joy and surprise to people who study astronomy. If you are a true lover of astronomical research, you can try this cool laser pointer.

Green laser pointers lower risk
The brightness of the green laser pointer is relatively objective, so the risk to the eyes is relatively high, and the higher the power, the more dangerous it is. Generally, 5mw is commonly used, and the US market allows 5mW laser pointer plus 5mw requires special approval. There are no restrictions in China, which requires us to pay special attention to the safety of users, not to shoot into the eyes or other vulnerable parts, and to prevent the reflected laser from passing through the eyes and entering the eyes. Focus-adjustable green generally doubles the protection switch.
However, one of the main challenges facing scientists and engineers is making blue high power laser pointer powerful and compact enough for use. Professor Edmund Linfield, Professor of Terahertz Electronics in the University's School of Electronics and Electrical Engineering, said: "While it is possible to make large-scale instruments capable of producing powerful beams of terahertz radiation, these instruments are not only suitable for limited applications. . We need terahertz Lasers must not only provide high power, but also be portable and low-cost." The first use of lasers in ordinary people's daily life was the supermarket barcode scanner introduced in 1974. The laser pointer disc player, introduced in 1978, was the first successful consumer product, and disc players that included a laser but were equipped with a laser were the first to become popular, starting in 1982, followed by laser printers.
