To use Table 1-2, look down the Air Temp column and locate an air temperature in Fahrenheit or Cel-
sius (°C values are shown in parentheses) that corresponds to the air temperature in the area where your
laser is operating. Follow this row across until you reach a column matching the relative humidity in your
location. The value at the intersection of the Air Temp and Relative Humidity columns is the Dew Point
Temperature in °F (or °C). The chiller’s temperature setpoint must be set above the dew point tempera-
ture. For example, if the air temperature is 85 °F (29 °C) and the relative humidity is 60%, then the dew
point temperature is 70 °F (21 °C). Adjust the chiller’s temperature setpoint to 72 °F (22 °C) to prevent
condensation from forming inside the laser.
Caution
possible
equipment
damage
Operating the laser at coolant temperatures above 22 °C (72 °F)
may result in decreased laser performance and/or premature failure of
electronic components.
