Projection distance (screen aspect ratio 4:3)
PT-LB3


PT-LB2V / PT-LB1V

* This distance is especially recommended for ceiling-mounted use and other permanent installations.

NOTE:
Values shown are approximate. The value for L (distance to screen) varies slightly depending on the zoom lens characteristics.
When the shortest projection distance is used, a small amount of distortion may occur in the image due to the zoom lens characteristics.

Calculation of the projection distance

For a screen size different from the above, use the equation below to calculate the projection distance.

PT-LB3
Aspect ratio 4 : 3 minimum
maximum		 L (m) = (diagonal screen size in inches) x 0.0292 – 0.025
L (m) = (diagonal screen size in inches) x 0.0351 – 0.033

PT-LB2V / PT-LB1V
Aspect ratio 4 : 3 minimum
maximum		 L (m) = (diagonal screen size in inches) x 0.0302 – 0.035
L (m) = (diagonal screen size in inches) x 0.0358 – 0.035

NOTE:
Distances calculated with the above equations will include a slight error.
