The Photron hollow cathode power supply provides a precision current source to correctly drive Photron hollow cathode lamps at a specific current. This allows use of a stand-alone hollow cathode lamp for purposes such as laser frequency tuning. Current is adjusted by a ten turn current control on the front panel. The current is constantly displayed on the front panel milliameter.
Current range is 0 to 25mA and a 600V automatic starting voltage is provided to enable even ageing lamps to start correctly.
