The fourth class: continuous high output laser (more than 500mW), higher than the third class, there is a risk of green laser pointer burn, can easily ignite cigarettes, matches and balloon burst, and even ignite all combustible materials laser pen high power. Pointer is extremely bright, strong interference against parasitic light, diffuse reflection is also risky, widely used in astronomical pointing, field measurement, field exploration, also used for automatic defense, is the preferred equipment for astronomy enthusiasts, outdoor enthusiasts. Wear safety glasses when playing high power laser point. In particular, laser is harmful to human eyes. Please do not directly illuminate human eyes and keep away from children to avoid accidental injury. Special reminder: This small size handheld laser pointer, super power, take into account the heat dissipation requirements, do not continue to use the powerful laser pointer for more than 30 seconds, otherwise easy to burn, can continue to use after a few minutes rest; Understand the correct battery installation method; Charge the battery for 1-2 hours. Do not charge it for a long time to avoid damaging the battery.
A new 589 nm yellow laser designator was introduced, which uses a more powerful and stealthy [specified] method to generate harmonics from the DPSS laser system. The "sodium" wavelength is only 4.5nm different from the old 593.5nm, but the color is more golden than the amber appearance of 593.5nm. The Observatory uses a specially modified 589.2 nm (yellow) dye laser to create laser guides for astronomical adaptive optics systems. DPSS high powered laser system.
