Table 7-1. Vision 65/75 Specifications (continued)

Brightness and Contrast:

Cinema Standards Measurement System (CSMS)

 

Specifications – Vision Model 65 Series

 

- Brightness*: 13.6 to 19.6 foot-Lamberts (fL)

 

- Contrast Ratio*: 200:1 to 220:1

 

Cinema Standards Measurement System (CSMS)

 

Specifications – Vision Model 75 Series

 

-

Brightness*: 14.8 to 21.7 foot-Lamberts (fL)

 

-

Contrast Ratio*: 200:1 to 230:1

 

*Variable depending on VAC setting

 

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 – Vision

 

Model 65 Series

 

- Light Output: 436 to 541 ANSI Lumens

 

- Contrast Ratio*: 200:1 to 220:1

 

Home Theater Calibration Specifications – Vision

 

Model 75 Series

 

-

Light Output: 451 to 589 ANSI Lumens

 

-

Contrast Ratio*: 200:1 to 230:1

 

These specifications are obtained by calibrating the projector as

 

described above for CSMS measurements.

 

Industry-Standard Specifications – Vision Model 65 Series

 

- Light Output: 1150 ANSI Lumens

 

-

Contrast Ratio: 3000:1

 

Industry-Standard Specifications – Vision Model 75 Series

 

-

Light Output: 1290 ANSI Lumens

 

-

Contrast Ratio: 11,000:1

 

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.

 

 

Lamp:

200 Watts

 

 

Estimated Lamp Life:

2000 hours

 

 

Video Inputs:

(1) Composite Video, (1) S-Video, (1) RGB/Component Video

 

(5 x BNC), (1) RCA Component Video (3 x RCA), (2) HDMI
