Laser module with focusing lens.
working voltage 4.5-5V
degree of protection IP20
working temperature -10 - 40 ° C
Please note that the laser module must not be conductively connected to any other metal part of another device during installation. It must be conductively insulated. Why is that so? In the vast majority of semiconductor lasers, the laser diode is pressed into a metal housing during production for better heat dissipation. Since one of the poles of the laser diode is fed to its housing, then this pole is also on the heatsink. To make things worse. The laser diode can be damaged even by a relatively small closing voltage. Use antistatic agents even when handling the laser.
TIP: In the worst case, reach for the radiator or water supply, which is certainly grounded in your house, before handling. Any static tension will be drained from your body. Avoid sweaters and similar types of clothing that can generate static electricity. Never connect the laser module conductively to another piece of metal.
This module does not require additional cooling. The laser has very low heat loss. So you do not have to worry about the insulation of the module and tight installation or mounting in a stand. In this case, the laser will not overheat and there will be no reduction in service life.
During operation, avoid any impact of the beam on the human or animal eye. The laser is not safe for human health.
