Eiki LC-W4 instruction manual Correcting the focus

Correcting the focus

When the lens is attached to the projector and images are being projected on the screen, the peripheral focus may be out of focus in some localized areas. If this happens, insert the accessory in between the lens attachment and the lens to correct the focus.

Inserting the spacers corrects the distance for the 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.
