3380 980nm 0.8W Infrared Dot Laser Module with TTL

Description3380 980nm 0.8W Infrared Dot Laser Module with TTLThis Infrared laser diode is an industrial electronic component and used for as Industrial test, Lab, DIY.This laser module can not work for a long time if there is no cooling device to keep the laser working under 30?.Please add a 5VDC power to this laser module. Red wire connects” ” pole; Black wire connects “-” pole. TTL 3-5V on, 0V off. If you don’t use TTL, please just leave the blue and white wire.This is a focusable laser module.

Otherwise to decease the power. But the current can not surpass the current we have set up.Please wear 980nm laser protection goggles to protect your eyes when working on this module.Note:The modules are tested and the output power are measured by laser power meter before sending out.Please don’t compare the power of this one with a none-measured laser.If you doubt the output, please have the laser you recieved checked by laser power meter. If there is any problem, please feel free to contact us. We will solve the problem asap. It is IR laser,the laser light cannot be seen by human bare eyes with only using DDC/infrared camera get it.
