Safety
Caution: Laser light emitted from any diode laser is invisible and may be harmful
to the human eye. Avoid looking directly into the diode laser aperture when the
device is in operation.
Note:
The use of optical instruments with this product will increase eye hazard.
Operating Considerations
ESD Caution
Always handle diode lasers with extreme care to prevent electrostatic discharge,
the primary cause of unexpected diode failure. You can prevent ESD by always
wearing wrist straps, grounding all applicable work surfaces, and following
extremely rigorous anti-static techniques when handling diode lasers.
Operating the diode laser outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used wit h the component must be employed such
that the maximum peak optical power cannot be exceeded. CW diode lasers may be damaged by excessive drive current or switching transients. When using power
supplies, the diode laser should be connected with the main power on and the output voltage at zero. The current should be increased slowly while monitoring the diode
laser output power and the drive current. Device degradation accelerates with increased temperature, and therefore careful attention to minimize the case temperature
As time goes by, people are increasingly concerned about their own and their families' health. However, existing monitoring devices for individual vital signs have struggled to gain market share du...[详细]
