The size of the 520nm Green Light Laser Dot Laser Module can be customized to meet your different requirements. The green dot is very clear, with Ultra-high brightness for indoor and outdoor use. The dots made under the outdoor sunlight are still clearly visible, Creating a clear and bright green beam in smoke or darkness. The brightness and line width of the laser light projected on different color backgrounds are different. We can provide some special lenses in addition to some commonly used dots, lines, and crosshairs.

Working Principle:

The difference between the green laser and the red laser is green lasers are much more complex than red lasers and require crystal conversion. The green light does not have a laser tube that emits green light can't directly but can only be converted by a crystal, and then expanded and collimated to produce well-focused green light.

520nm Green Light Laser Dot Laser Module working principle of semiconductor lasers is the excitation method. Using semiconductor materials, that is, using electrons to transition between energy bands to emit light, using the cleavage surface of the semiconductor crystal to form two parallel mirror surfaces as mirrors, forming a resonant cavity, so that the light oscillates, feeds back, and generates the radiation of light to amplify the output laser.

Laser Drive Circuit:

The driving circuit module of the laser can be APC (Automatic Power Control) or ACC (Automatic Current Control). The APC control laser module will automatically adjust the input current to a constant value of the output optical power. The ACC-controlled laser module will have a constant value for the input current in another way, while the output power may vary. In addition to CW mode (continuous wave mode), our laser modules can input a TTL modulation. It can be fixed at a certain operating frequency (Hertz) or a specific duty cycle or can be alternated by external PWM input, etc.
