Barco F50 - Throw Distance

5. Installation
5.7 Throw distance
Calculating the installation throw distance
Throw is the distance (D) measured from y our projector lens to the screen. To calculate the throw distance for an installation, you
will need two pieces of data: the selected lens throw ratio (L) and the horizontal width (W) of the screen.
For example, if the screen width (W) is 2 .4 meters and the projector lens has a throw ratio (L) of 0.99:1, then the t hrow distance (D)
will be 2.38 m eters.
Calculation: 2.4 x 0.99 = 2.38
The following gr aphs illustrate the image size ( W ) and projection distance (D) for each of the projector lenses.
Tolerances are typically +/- 5% due to optical (lens) variation.
