χ: Picture size (diag.) (in/cm)

L:Projection distance(m/ft)

L1: Minimum projection distance (m/ft)

L2: Maximum projection distance (m/ft)

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

S:Adjustable range of image position (cm/in)

The formula for picture size and projection distance

[m/cm]

L1 (m) = 0.0731χ

L2 (m) = 0.11274χ

H(cm) = 0.04151χ S (cm) = ±0.20754χ

[Feet/inches]

L1 (ft) = 0.0731χ / 0.3048

L2 (ft) = 0.11274χ / 0.3048 H (in) = 0.04151χ / 2.54 S (in) = ±0.20754χ / 2.54

Note

•Allow a margin of error in the value in the diagrams above.

•When the distance from the lens center to the bottom of the image [H] is a negative number, this indicates that the bottom of the image is below the lens center.
