Laser diode module

Laser diode module
Usually the internal structure of the laser module is:
The laser diode is equipped with a constant current driving circuit to realize the laser light emission, and then the laser and the lens system are used to realize the focusing and expanding of the laser.

They are then installed in a metal casing. This laser module has higher mechanical strength, is easy to install, anti-interference and not easy to damage.

A laser module with high power and high heat is also equipped with a small fan for heat dissipation.
