Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 4:3
Zoom lenses
ET-ELW06
minimum
L (m) = (diagonal screen size in inches) × 0.024389 – 0.065097
maximum
L (m) = (diagonal screen size in inches) × 0.031710 – 0.099560
ET-ELW02
minimum
L (m) = (diagonal screen size in inches) × 0.028982 – 0.089642
maximum
L (m) = (diagonal screen size in inches) × 0.037722 – 0.089627
ET-ELW04
minimum
L (m) = (diagonal screen size in inches) × 0.032144 – 0.139232
maximum
L (m) = (diagonal screen size in inches) × 0.041988 – 0.123040
ET-ELS02
minimum
L (m) = (diagonal screen size in inches) × 0.042086 – 0.208493
maximum
L (m) = (diagonal screen size in inches) × 0.054690 – 0.203992
ET-ELS03
minimum
L (m) = (diagonal screen size in inches) × 0.053914 – 0.175760
maximum
L (m) = (diagonal screen size in inches) × 0.072616 – 0.163096
ET-ELM01
minimum
L (m) = (diagonal screen size in inches) × 0.069440 + 0.086800
maximum
L (m) = (diagonal screen size in inches) × 0.089871 + 0.086816
ET-ELT02
minimum
L (m) = (diagonal screen size in inches) × 0.087982 + 0.221978
maximum
L (m) = (diagonal screen size in inches) × 0.123396 + 0.173741
ET-ELT03
minimum
L (m) = (diagonal screen size in inches) × 0.122945 + 0.350492
maximum
L (m) = (diagonal screen size in inches) × 0.180688 + 0.343253
Fixed-focus lens
ET-ELW03
minimum
L (m) = (diagonal screen size in inches) × 0.016666 – 0.067361
