What is focus light?
We all know that focus needs to be done before the device starts to work, the focus light brightness is for you to set the laser to a very low brightness while the device is focusing, this will help you focus
Why to change focus light?
The focus brightness is achieved by the controller outputting a very low PWM duty, such as 0.01%, but the laser brightness emitted by the same PWM of different lasers is different. If it is too bright or too dark, it will cause inconvenience to focus. This is the reason why to change focus light.
