**Manufacturer:** 3B Scientific  
**MPN:** `U19153`

The 3B Scientific U19153 Teltron Maltese-Cross Electron Tube D is a high-vacuum electron tube. It features a divergent electron gun aimed at a fluorescent screen partially obscured by a Maltese cross, demonstrating the linear propagation of electrons in the absence of applied electromagnetic fields. The shadow of the Maltese cross is projected onto the fluorescent screen, allowing for the study of electron optics, such as beam focusing.
