To determine the projection distance when you know the diagonal size of the screen image:
❐Inches:
Maximum projection distance = (3.492 × diagonal size) - 5.091 Minimum projection distance = (2.053 × diagonal size) - 4.795
❐Centimeters:
Maximum projection distance = (8.8696 × diagonal size) - 12.9311 Minimum projection distance = (5.214 × diagonal size) - 12.1793
Short Throw Zoom Lens Calculations (ELPLW01)To determine the maximum and minimum diagonal size of an image when you know the projection distance:
❐Inches:
Maximum diagonal size = (0.876 × projection distance) + 3.793 Minimum diagonal size = (0.730 × projection distance) + 3.029
❐Centimeters:
Maximum diagonal size = (2.2250 × projection distance) + 9.6342 Minimum diagonal size = (1.8542 × projection distance) + 7.6936
To determine the projection distance when you know the diagonal size of the screen image:
❐Inches:
Maximum projection distance = (1.369 × diagonal size) - 4.147 Minimum projection distance = (1.142 × diagonal size) - 4.331
❐Centimeters:
Maximum projection distance = (3.4772 × diagonal size) - 10.5333 Minimum projection distance = (2.9006 × diagonal size) - 11.0007
