What is the optical axis angle?
The optical axis angle is the angle between the horizontal level line and the
straight line from the center of the projector’s green lens to the center of
the screen. When using a rear projection screen, you can get the brightest

extension of the center of the green lens.
Therefore, the most suitable optical axis angle varies depending on the
height of the screen and your line of sight.
When the optical axis angle is 2
