Description
1
Nitrogen Purge
Inlet/Outlet
These are the fittings for the required nitrogen purge gas. With no purge, ozone will form
from atmospheric oxygen and attenuate the light output in the 220
–
280nm band. In addition,
atmospheric oxygen and water vapor will attenuate the output below 200nm
2
Cooling Water Inlet /
Outlet
These fittings are for connection of cooling water required by the Lamp.
3
Control Connector (9-pin
D-sub)
Provides various power and control signals to/from the Power Supply Controller. No other
connector or cable may be used with the EQ-400 other than the one supplied.
