Checking Procedure
1. Set the projection distance of the lens projector. (Refer to “Reference value”)
2. Set the focus.
3. Bring the projector into focus so that fine lines of the center projected image (y’ = 0) on the screen can be clearly seen as much as possible
by operating the program screen.
Saggital (S)
Meridional (M)
The number of projective
resolving power lines
Use the small projected image.
