Luminescence Tube D, 1000648 [U19152], Electron Tubes – Type D
305.00 €
Experiment Topics: ..
The following topics can be discussed with this highly evacuated tube: 
•  Luminescence of different phosphors when excited by electrons (cathodoluminescence)
•  Luminescence of different phosphors when excited by ultraviolet light (photoluminescence).
•  Phosphorescence and quenching

Product Information: ..
The luminescence tube is a highly evacuated tube with an electron gun consisting of a pure tungsten heater filament inside an apertured “cathode can” and a cylindrical anode contained in a clear glass bulb. A screen with three mica flags with different phosphors is mounted on a metal support.
The luminescence tube serves to demonstrate the luminescence of different phosphors when excited by electrons (cathodoluminescence) or ultraviolet light (photoluminescence).

Specifications: ..
Filament voltageUF : 6.3 V AC/DC
Anode voltage UA : max. 5000 V DC approx.
Anode current IA : 180 µA at 4000 V, approx.
Glass bulb: 130 mm Ø approx.
Total length: 260 mm approx.
