Projection Distance
The projection distance is the distance from the front surface of the lens to the projection surface.
The projection screen height is the distance from the point of intersection (A in the image) of the line drawn perpendicular to the surface projected from the lens center and the projection surface, to the lower edge (upper edge when installed to the ceiling) of the projection screen.
For this projector, the projection distance value for when the projector is installed to the floor and to the ceiling is the same.
When installed to the floor/ceiling (install so that the projector upper surface is parallel with the ceiling)
A: The point of intersection of the line drawn perpendicular to the surface projected from the lens center and the projection surface
B: Projection screen
C: Lens front surface
H: Projection screen height position
L: Projection distance
