Photron Hollow Cathode Lamp Power Supply

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, Astronomy with P858A Thorium Lamps and Optogalvanic Lamps as well.

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 aging lamps to start correctly.
