Question

Which of the following is the component of the image intensifier responsible for focusing the electron beam?

a.) Electrostatic Lens
b.) Glass envelope
c.) Input phosphor
d.) Output phosphor
e.) Photocathode

Answer 1

The electrostatic lens is responsible for focusing the electron beam in an image intensifier.

Step-by-step explanation:

The component of the image intensifier responsible for focusing the electron beam is the electrostatic lens. This component functions by using static electric fields to guide and focus the electron beam from the photocathode to the output phosphor. The focusing ability of electrostatic lenses is critical for ensuring that the intensified image maintains the correct geometric proportions and resolution.

The component of the image intensifier responsible for focusing the electron beam is the Electrostatic Lens. The electrostatic lens uses electric fields to control the path of the electron beam and focus it onto the desired area.
