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 DMD™ resolution of your projector
•
The distance between the projector and the screen
(throw distance)
•
The maximum width of your screen
In the chart for the required DMD™ resolution, find the
point where the throw distance corresponds to the screen
width, as shown in the example below.
Example
For a 1080p projector with
•
throw distance 14 m, and
•
screen width 3.5 m,
the correct lens would be number 6 in the chart.
Notes
For information about individual
lens part numbers, see
