07.10.2011 VLM650-04-LPT 2 of 2 outline dimension : unit: mm cautions 1. do not operate the device above the macimum rating condition, even momentarily. it may cause unexpected permanent damage to the device. 2. 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 sercice periode. therefor, proper measures for precenting electrostatic discharge are strongly recommended. 3. do not look into the laser beam directly with the naked eyes. the laser beam may cause severe damage to human eyes.
