Working Principle of Red Laser Module

The laser module works using a semiconductor laser diode that emits coherent red light at 650nm. When power is applied, the diode produces a focused laser beam. The adjustable lens allows the user to modify the beam width and focal distance.

This simple yet effective mechanism makes the module ideal for projects where precise light direction and visibility are required.

Adjustable Focus Advantage

The adjustable lens provides flexibility to:

• Focus the beam to a sharp point

• Spread the beam for line projection

• Adapt to different distances

• Improve alignment accuracy

This feature significantly increases the module’s usability across multiple applications.
