Guideline for use
Use the appropriate lens for a combination of projector installation position and
screen size.
• See the figure below for the standard lens, LV-IL02 (wide angle zoom lens) and LV-
IL03 (long focus zoom lens).
Fig. 1-3
For example, use a long focus lens to project an image to a 200 type screen
installed at a distance of 12m.
• LV-IL01 (ultra wide zoom lens) can be used for front projection. If it is installed for
front projection, the projector overlaps with the center of the screen. Therefore, it
should be used for rear projection.
