LASER MAINTENANCE
and the system is operating at the specified power. Peak values are shown in all cases and efficiencies will vary between
systems of different wavelengths.
Maximum at 240 V supply – using the supplied External Power Supply Source:
120 W
At the 12 V input the SMD24 can draw maximum of 8 A

Example: 473 nm system, operating at 175 mW will consume 60 W maximum and 45 W typical
The heat dissipation of the laser head is approximately 60% of the total power consumption.
Laser Maintenance
If the gem is operated in a smoky or dirty environment, occasional cleaning of the laser window may be necessary. To
perform this procedure, the laser must be turned off and, using optical cloth dampened with research grade methanol, the
laser window must be gently wiped.
Always follow the instructions given in this Operating Manual
•
Always use the PSU which was delivered with the laser and do not attempt to control the laser with any other PSU
•
Ensure laser is firmly fixed to an appropriate heatsink to allow efficient heat dissipation from the laser head and
•
ensure a thermal equilibrium is achieved. The laser should be held in an environment with temperature stability
±0.1°C to achieve the marketed specifications. Use the laser head power consumption figures to help determine
what heat-sink dissipation is needed or speak with your sales representative
Never touch the connector on the laser head with anything other than the Umbilical cable provided and always
•
follow the connection instructions in this Operating Manual
Do not open the laser head or PSU; this will immediately invalidate the warranty
•
Do not subject the laser head to mechanical shock; if severe this can cause mis-alignment of the laser cavity
•
Do not allow the output window of the laser to be touched as this may damage the precision optical coatings
•
used. Avoid very dirty atmospheres where dirt may settle on the window
Do not operate or store this laser system in very humid or damp environments
•
Guaranteed specification will only be achieved at the ordered power level. Laser calibration may not always be accurate at
very low powers – for alignment purposes seek external attenuation.
