Calculation of the projection distance

S P E C F I L E

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

Aspect ratio 15:9

ET-DLE100	minimum	L (mm) = (diagonal screen size in inches) x 30.0 – 45
	maximum	L (mm) = (diagonal screen size in inches) x 40.4 – 48
ET-DLE150	minimum	L (mm) = (diagonal screen size in inches) x 30.4 – 54
	maximum	L (mm) = (diagonal screen size in inches) x 43.8 – 50
Supplied lens	minimum	L (mm) = (diagonal screen size in inches) x 40.2 – 65
	maximum	L (mm) = (diagonal screen size in inches) x 53.0 – 64
ET-DLE200	minimum	L (mm) = (diagonal screen size in inches) x 54.7 – 66
	maximum	L (mm) = (diagonal screen size in inches) x 89.5 – 76
ET-DLE250	minimum	L (mm) = (diagonal screen size in inches) x 53.0 – 80
	maximum	L (mm) = (diagonal screen size in inches) x 83.8 – 79
ET-DLE310	minimum	L (mm) = (diagonal screen size in inches) x 78.6 – 106
	maximum	L (mm) = (diagonal screen size in inches) x 102.6 – 105
ET-DLE350	minimum	L (mm) = (diagonal screen size in inches) x 83.6 – 135
	maximum	L (mm) = (diagonal screen size in inches) x 126.3 – 135
ET-DLE410	minimum	L (mm) = (diagonal screen size in inches) x 104.4 – 137
	maximum	L (mm) = (diagonal screen size in inches) x 195.1 – 135
ET-DLE450	minimum	L (mm) = (diagonal screen size in inches) x 126.6 – 302
	maximum	L (mm) = (diagonal screen size in inches) x 200.1 – 299
ET-DLE050	(fixed focus)	L (mm) = (diagonal screen size in inches) x 18.0 – 36
ET-DLE055	(fixed focus)	L (mm) = (diagonal screen size in inches) x 18.6 – 48

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

•When an SXGA signal is input, the left and right edges of the image are blanked, and the image is projected at a screen aspect ratio of 5:4.

•The brightness varies depending on the zoom setting.
