The stages are the condensor lenses, the objective lenses, and the projector lenses.

The projector lenses are used to expand the beam onto the phosphor screen or other imaging device, such as film.

The projector lenses allow for the correct positioning of this electron wave distribution onto the viewing system.

Sometimes people think it's dirt on the projector lens.

However, now the electrons travel away from the condenser optics and into the projector lenses.

Contrast aperture, located in the center on the projector lens side of the beam separator.

They still produce anamorphic projector lenses and adapters for the Schneider group, including three models which are similar in appearance to the Iscorama 54:

Some areas of the screen may not be focused correctly as the projector lens is focused at the average distance only.

Most one-projector systems use a special polarization switch mounted over the projector lens.

They adjusted the projector lens and position to get the transshipment platform of Psychlo more centered and enlarged.
