The following table details the information required to calculate the lens throw ratios for the Christie LWU530-APS and LWU650-APS
projectors.
Throw distance formula Vertical and
horizontal
Diagonal screen sizes
Lens Imperial (in) Metric (cm) Offset (%) Imperial (in) Metric (cm)
1.4-2.4 :1 fixed zoom TDmin = 1.434 x W - 4.72 TDmin = 1.434 x W -11.9861 0 to +56.5% V 30 to 300 76.2 to 762
TDmax = 2.4543 x W - 4.82 TDmax = 2.4543 x W - 12.2509 ± 4.6% H
• Throw distance measured from the center of the front foot of the projector.
• All lenses are made of glass.
• Calculated throw distance (TD) values are subject to a +/- 5% tolerance for individual lens variation.
• Calculated offset values are subject to a +/- 7% centering tolerance.
