EPSON PowerLite 8000i/9000i Projector
To determine the projection distance when you know the
diagonal size of the screen image:
Inches:
Maximum projection distance = (1.967 diagonal size) – 3.224
Minimum projection distance = (1.554 diagonal size) – 3.563
Centimeters:
Maximum projection distance = (4.996 diagonal size) – 8.1889
Minimum projection distance = (3.947 diagonal size) – 9.0500
For example, here are the measurements for three installations:
Image size
(diagonal)
Minimum
300 in.* (762 cm)
460.6 in. (11.7 m)
200 in. (508 cm)
307.1 in. (7.8 m)
100 in. (254 cm)
153.5 in. (3.9 m)
* For an image size of 320 inches, the projector may be up to 52.1
feet away from the screen, depending on the setting of the zoom
ring.
Long Throw Zoom Lens Calculations (ELPLL02)
To determine the minimum and maximum diagonal size of an
image when you know the projection distance:
Inches:
Maximum diagonal size = (0.487 projection distance) + 2.336
Minimum diagonal size = (0.286 projection distance) + 1.458
Centimeters:
Maximum diagonal size = (1.2369 projection distance) + 5.9334
Minimum diagonal size = (0.7264 projection distance) + 3.7033
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 = (1.554 diagonal size) – 3.563
Centimeters:
Maximum projection distance = (8.8696 diagonal size) – 12.9311
Minimum projection distance = (3.9471 diagonal size) – 9.0500
Short Throw Zoom Lens Calculations (ELPLW01)
To determine the minimum and maximum 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
