Table 7-1. Vision 140/150 Specifications (continued)

Brightness and Contrast:	Cinema Standards Measurement System (CSMS)
	Specifications
	-	Brightness: 86.5 foot-Lamberts (fL) (Vision 140);
		102.0 fL (Vision 150)
	-	Contrast Ratio (variable, based on lens aperture setting):
		235:1 - 275:1 (Vision 140); 224:1 - 275:1 (Vision 150)
	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: 2750 ANSI Lumens (Vision 140);
		3517 ANSI Lumens (Vision 150)
	-	Contrast Ratio (variable, based on lens aperture setting):
		235:1 - 275:1 (Vision 140); 224:1 - 275:1 (Vision 150)
	These specifications are obtained by calibrating the projector as
	described above for CSMS measurements.
	Industry-Standard Specifications
	-	Light Output: 4000 ANSI Lumens (Vision 140);
		6000 ANSI Lumens (Vision 150)
	-	Contrast Ratio (variable, based on lens aperture setting):
		1500:1 - 2000:1
	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.
