Projection dimensions calculation methods

If the screen size (diagonal) is SD (m), then the following formula is used to calculate the projection distance for the wide lens position (LW) and the projection distance for the telephoto lens position (LT).

		4:3
		SH
		H1
	LW/LT	SW
	PT-LB20NTE/PT-LB20E	LW=0.030xSD/0.0254-0.037
	PT-LB20NTE/PT-LB20E	LT=0.036xSD/0.0254-0.037
		LT=0.036xSD/0.0254-0.037
	PT-LB20SE	LW=0.031xSD/0.0254-0.038
	PT-LB20SE	LT=0.037xSD/0.0254-0.038
		LT=0.037xSD/0.0254-0.038
	PT-LB20VE	LW=0.035xSD/0.0254-0.037
	PT-LB20VE	LT=0.042xSD/0.0254-0.036
		LT=0.042xSD/0.0254-0.036

For 16:9 aspect ratios, the following formula can be used to calculate the projection distance.

PT-LB20NTE/PT-LB20E

LW=0.032xSD/0.0254-0.037

LT=0.039xSD/0.0254-0.037

PT-LB20SE

PT-LB20VE

LW=0.033xSD/0.0254-0.038

LT=0.040xSD/0.0254-0.038

LW=0.038xSD/0.0254-0.037

LT=0.046xSD/0.0254-0.037

*The values obtained from the formulas above are approximate.
