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, nd 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 28 m, and
• screen width 7 m,
the correct lens would be number 7 in the chart.
Notes
For information about individual lens
part numbers, see Appendix A:
