Focus balance
Relationship between the tilt of the lens and the screen focus surface
When the projection lens is tilted in contrast with the image forming surface, tilting the front side (screen side)
of the projection lens downwards (in the direction of the dotted arrow line), the upper side of the screen focus
surface will tilt inwards and the lower side will tilt outwards as shown in the example.
