Correcting the focus
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 areas. If this happens, insert the spacer of attachment to a projector 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 with
approximately 30 mm for each 0.1-mm thickness of the spacers.
Three types of spacers, four of each spacer type, are supplied. Insert these spacers to correct the distance as
required.
