Useful lens calculations
Examples of lens calculations
Use the information in Appendix A at the end of this Reference Guide to identify the exact lens needed.
Image size 1024 x 768 pixels, screen width 6.5m, throw distance 18m from\
the outer end of the lens.
• Throw ratio factor (TRF) = 1920 / 1024 = 1.875
• Throw ratio required = 18 / (6.5 x 1.875) = 1.48
Choose the 1.45 - 1.75 : 1 zoom lens.

Any single adjustment outside the ranges specified on the following page may result in an unacceptable level of distortion, particularly at the
corners of the image, due to the image passing through the periphery of \
