To
find the screen width and having only the
throw distance, use the following equation.
Throw distance / Ratio = Screen width
I.e.. The projector is 20
feet from screen. The PLC-9000N standard lens ratio is
1.8~2.9:1 |
|
20'
divide by 1.8 = 11.1' screen width
20' divide by 2.9 = 6.9' screen width
So at 20' from the screen: |
the
min. screen width is 6.9'
the max. screen width is 11.1'
|
| 2) |
To
find the throw distance and having only
the screen width, use the following equation.
Screen width x Ratio = Throw
distance
I.e.. The projector image is
20 feet wide. The PLC-9000N standard lens ratio is
1.8~2.9:1 |
|
20'
screen width x 1.8
20' screen width x 2.9
To get a 20' wide image: |
(Ratio)
= 36' (throw distance)
(Ratio) = 58' (throw distance)
the min. throw distance is
36'
the max. throw distance is 58' |
