Brightness and Contrast

Cinema Standards Measurement System (CSMS)

(variable, depending on VAC

Specifications

calibration):

-

Brightness: 16.1 to 25.2 foot-Lamberts (fL)

 

-

Contrast Ratio (variable, based on lens aperture setting):

 

 

215:1 - 234:1

 

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: 430 - 648 ANSI Lumens

 

-

Contrast Ratio (variable, based on lens aperture setting):

 

 

215:1 - 234:1

 

These specifications are obtained by calibrating the projector as

 

described above for CSMS measurements.

 

Industry-Standard Specifications

 

-

Light Output: 1600 ANSI Lumens

 

-

Contrast Ratio (variable, based on lens aperture setting):

 

 

2700:1 - 3350:1

 

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.

 

 

Power Requirements:

100 to 240 VAC (auto-sensing), 50/60 Hz, 375 Watts

 

 

Operating Environment:

40°F to 95°F (5°C to 35°C), 0% to 90% humidity

 

(non-condensing)

 

 

Dimensions:

See Figure 7-1

 

 

Weight (without lens):

50 lbs. (22.68 kg)

 

 

Regulatory Approvals:

Complies with FCC, CE C-Tick

 

 

Limited Warranty:

Projector: Two (2) years parts and labor from the date of delivery

 

to the end user.

 

Lamp: 1000 hours or six (6) months, whichever comes first.

 

 

 

Specifications are subject to change without notice.
