What are the components of a laser pointer?
Inside the Laser pointer is a semiconductor laser, a type of LED. Generally, an optical lens is added in front to focus. Lasers are very concentrated and harmful to human health. It should not be directed at the human body, especially the eyes, which will cause damage to the eyes. The danger of blindness. The laser pointer mainly consists of a power supply (battery), a constant current drive circuit (LD driver), a laser diode, a lens and a shell. There is also the laser design into a pen emitter, pen emitter is designed to be portable, easy to carry, and processing into laser module (led).

The working principle of laser pointer is composed of radio frequency remote controller and receiver (USB interface). The RF remote control has an rf transmitter built in. To use, just plug the receiver into the USB interface of the host. No need to install the driver can work normally, users only need to click the relevant function keys of the RADIO frequency remote control to operate the receiver. And the transmitter doesn't need to be aimed at the receiver, which is true wireless freedom.The working principle of laser pointer is composed of radio frequency remote controller and receiver (USB interface).

The base part is a laser emitter, and the pen in the hand is used to write in the air. The base detects the nib's position and fires a laser beam at it 100 times per second, creating glowing ion spots in mid-air. The ion dots combine to form a floating beam. This allows users to paint in the air.
