Focus correction
When the lens is attached to the projector and images
are being projected onto the screen, the peripheral
focus may be out of focus in some localized areas. If
this happens, insert the one, of three sizes of spacers,
in between the Lens Attachment and the lens to adjust
the focus.
Inserting the Spacer corrects the distance on the Lens
Adjustment and improves the diagonal focus.
The corrected distance is determined by the thickness
of the used spacers. As a guide, the distance is
adjusted by approximately 30 mm for each 0.1-mm
thickness of the spacers.
There are three types of spacers provided, and there
are four of each spacer type. Use these spacers to
correct the distance as required.
