A change in the characteristics of the laser or premature failure may result. * Proper heat sinking of the device assures stability and lifetime. Always ensure that maximum operating temperatures are not exceeded. * Observing visible or invisible laser beams with the human eye directly, or ...
* Semiconductor laser device is very sensitive to electrostatic discharge. High voltage spike current may change the characteristics of the device, or malfunction at any time during its service period. Therefore, proper measures for preventing electrostatic discharge are strongly recommended. * To obtain...
