Appendix B: Lens Charts
How to use the lens charts
The lens charts on the following pages provide a quick guide to the
type of lens needed for a particular projector.
To use the lens charts, you need the following information:
•
The distance between the projector and the screen (throw
distance)
•
The maximum width of your screen
In the chart, find the point where the throw distance corresponds to
the screen width, as shown in the example below.
Example
For a projector with
•
throw distance 7 m, and
•
screen width 3.5 m,
the correct lens would be number 3 in the chart.
Notes
For information about individual
lens part numbers, see
