There are times when we want to use laser lights in our projects. These lights are theoretically perfectly parallel and the intensity remains concentrated in the axis of traversal of light. A laser module is very easy to use, you can use Arduino control, do controllable laser pointer, theft detection, etc. interesting application devices.
The laser head is composed of a light-emitting tube, condenser lens and adjustable copper sleeve and it is assembled when delivered, the focal length of the lens is adjusted by a strong glue stick, which can work directly after connecting to a 5V DC power supply.

Safety Measures to follow
1. Never put eyes directly in the path of traverse of light.
2. Use appropriate protection devices to prevent exposure of high beam light.
