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.
