Caution! Don't look at the laser beam directly, because it's harmful to eyes. 2. The storage temperature is between –40 and 85 °C. 3. Under normal circumstances, the higher the temperature is, the shorter the life of semiconductor laser will be. It is recommended to use lasers under TEC cooling or in air-conditioned ro...
