  1. The laser light emitted by the laser module is likely to injure persons'eye, so do not directly gaze its end surface and wear appropriate safety glasses to prevent laser light when it is working.

  2. Laser module needs an appropriate laser driver(PCB). When the laser module connects with power supply, please set the output voltage to zero. The adjustment of the current should be slowly increased or decrease to avoid damaging the device.

  3. Keep the device working or storing in a dry environment. The anti-dust grade is over one million, in order to prevent dust inside the lens to affect the laser dot shape.

  4. Working at high temperatures will increase the threshold current, reduce conversion efficiency and speed up the aging of the device.

  5. When output power is higher than it's specific parameter of operation, it will accelerate the aging of the device.

  6. When the operation temperature of the laser diode is over 70degree, please do well heat dissipation of it.

  7. This laser module is an electrostatic sensitive device. Please make sure ground yourself or wear an antistatic wrist strap before you take it.
