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 spacer
in between the lens attachment and the lens to
correct the focus.
Correcting the focus
Spacer "1"
Color; Clear
Thickness; 0.1 mm

Inserting the spacers corrects the distance for best
diagonal focus at the screen.
The corrected distance is determined by the
thickness of the spacers that are used. 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.
