χ: Picture (Screen) size (diag.) (in/cm)

The formula for picture size and projection distance

L: Projection distance (ft/m)

[Feet/inches]

[m/cm]

L1: Minimum projection distance (ft/m)

L1 (ft) = 0.02771χ / 0.3048

L1 (m) = 0.02771χ

L2: Maximum projection distance (ft/m)

L2 (ft) = 0.03206χ / 0.3048

L2 (m) = 0.03206χ

H: Distance from the lens center to the bottom of the image (in/cm)

H (in) = 0.16346χ / 2.54

H (cm) = 0.16346χ

S: Adjustable range of image position (in/cm) See page 47.

S (in) = ± 0.0381χ / 2.54

S (cm) = ± 0.0381χ

Note

Refer to page 18 concerning “Projection distance [L]” and “Distance from the lens center to the bottom of the image [H]”.

Allow a margin of error in the values in the diagrams.
