Table 7-1. Vision 90t/100t Specifications (continued)

Brightness and Contrast:	Cinema Standards Measurement System (CSMS)
	Specifications
	-	Brightness:
		45.3 foot-Lamberts (fL) (Vision Model 90t);
		78.5 foot-Lamberts (Vision Model 100t)
	-	Contrast Ratio:
		258:1 (Vision Model 90t);
		228:1 (Vision Model 100t)
	These measurements are taken from the projector in a controlled,
	home theater environment. All measurements are made to
	ANSI/NAPM IT7.228-1997 specifications using the Photo Research
	PR-650 SpectraColorimeter and Minolta LS-100 Luminance Meter,
	Video Essentials test DVD and a 1.3 gain, 72-inch wide screen. The
	projector is calibrated to a color temperature of 6,500K and has a
	minimum of 150 hours of usage.
	The foot-Lambert (fL) is the unit of measurement used in commercial
	movie theaters to express image brightness at the screen surface.
	The Society of Motion Picture and Television Engineers (SMPTE)
	specifies 16 fL as the target image brightness for film-based
	projectors using an open gate (without film in the projector). More
	importantly, today SMPTE specifies 12 fL as the target image
	brightness in Digital Cinema theaters. The foot-Lambert
	measurement is dependent on screen size, screen gain and projector
	light output.
	Home Theater Calibration Specifications
	-	Light Output:
		1120 ANSI Lumens (Vision Model 90t);
		2631 ANSI Lumens (Vision Model 100t)
	-	Contrast Ratio:
		258:1 (Vision Model 90t);
		228:1 (Vision Model 100t)
	These specifications are obtained by calibrating the projector as
	described above for CSMS measurements.
	Industry-Standard Specifications
	-	Light Output:
		2250 ANSI Lumens (Vision Model 90t);
		3500 ANSI Lumens (Vision Model 100t)
	-	Contrast Ratio:
		3000:1 (Vision Model 90t);
		2000:1 (Vision Model 100t)
	These are typical projector brightness and contrast specifications
	found in most companies’ sales literature. Vidikron includes these
	measurements in its literature to allow for direct comparison with
	other manufacturers’ projectors. These measurements are typically
	taken at 9,000K to 13,000K to get expected performance data when
	the projector is used in professional, commercial and industrial
	displays.
