Laser operating temperature range
Green area: The dew point temperature is
22℃
that is lower than the laser
cooling water temperature, which can be used safely
；
Red area: If the dew point temperature is higher than
22℃
and exceeds the
laser cooling water temperature by
22℃
, there must bedew condensation,
and measures must be taken.
Measure 1: Dehumidifier works for 10-15 minutes in standby mode(laser
power and cooling water should be on state );
Measure 2: Installing cabinet air conditioner to reduce ambient
temperature.
