Cinema Standards Measurement System (CSMS) 
Specifications
-

Brightness: 86.0 foot-Lamberts (fL) (VX-40d); 
107.3 fL (VX-50d); 94 fL (VX-60d); 188.6 fL (VX-80d) 

-

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

 

233:1 - 285:1 (VX-40d); 
229:1 - 279:1 (VX-50d); 

 

227:1 - 282:1 (VX-60d); 

 

225:1 - 277:1 (VX-80d) 

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.

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

 

1500 - 2000:1

These are typical projector brightness and contrast specifications 
found in most companies’ sales literature. Runco 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.
