Industrial 520nm 15mw Green Laser Module Dot/Line/Cross 1240 Industrial 520nm 15mw Green Laser Module Dot/Line/Cross 1240This product makes use of imported LD, which directly generates inexperienced light, the laser wavelength is 520nm, the sunshine color is pure, and the functionality is stable. Widely used in sights, cellular positioning and different package Product Usage:The emission principle and production technique of the laser opt that the laser has the characteristics that normal light does not have: that is, 3 nice (good monochromaticity, good coherence, nice directionality) and one excessive (high brightness). Using the best directionality and high brightness of the laser, it may be broadly used in military, counterfeiting, security, level (red, green, blue) lighting, diverse energy tools, measuring, instruments, equipment, spirit levels, locators, measuring devices Distance meter, thermometer, laser marking device (line casting instrument), digital application measuring tool, mouse, U disk, video camera, cellular phone, projection teaching page-turning pen, laser pointer, handicraft, indoor and outside decoration, flashlight, present Classes, toys and other products.
