Laser module, also called laser module, consists of laser tube and laser head module. The rough light module is a laser that can produce a wide-angle beam. When we use the rough light module and the smoke machine at the same time, we can see an obvious light pillar.
The principle of laser beam expansion is to use optical elements such as lenses or other optical elements to change the diameter and divergence angle of the laser beam. The size and divergence angle of the laser beam within a spot can be changed by using lenses of different shapes and sizes. When a laser beam passes through a lens, the shape and focal length of the lens refract and focus the beam, thereby changing the diameter and divergence angle of the laser beam. The diameter and divergence angle of the laser beam depend on the characteristics of the laser, the design of the optical system, and the lenses or optics used.
There are many types of rough light modules: 650nm red laser; 520nm green laser; 450nm blue laser and other visible light colors. The use of lasers needs to strictly comply with relevant laser safety level standards and cannot directly irradiate human eyes.
The rough light module is a new type of laser module that can provide customers with unique light effects and visual effects. It features high power, high precision, high beam quality and long life. By changing parameters such as multiple laser beam colors, different brightness and distribution, different nighttime landscapes and atmosphere effects can be created. Therefore, it is widely used in ambient lighting, bar lights, stage lights, warning lights, landmark landscape lights and lawn lights.
