Christie 1,8-2,8:1 standard lens for DHD800

Projection ratio:
The projection ratio indicates at which projection distance a corresponding image width is achieved. This value depends on the lens installed.Example 1 - Calculating the distance: Projection ratio 1.4-1.8:1 Desired image width = 300cm Result: 420 - 540 cm distance (300 x 1.4 or 1.8). Example 2 - Calculation of possible image widths: Projection ratio 1.4-1.8:1 Projection distance = 560cm Result: 311 - 400cm image width (560 / 1.4 or 1.8).
