Description

X-Rite SpectraLight QC Attenuator

Attenuator acts as a filter that cuts out the light output in Algorithm way depending on the percentage. They are easy to replace daylight lux attenuators (snap in mechanism). Make sure the setting matches the attenuator cover installed otherwise the system will not work properly.

 

  • 25% attenuation is 75% lux output.
  • 50% attenuation is 50% lux output
  • 75% attenuation is 25% lux output

 

Attenuator 0% Lux Output 25% Lux Output 50% Lux Output 75% Lux Output
D50 D50 illuminantA near white light source used in the evaluation of graphic arts and imaging applications. Also used as reference illuminant for color matching in LAB color space.

It has similar amounts of red, green, and blue energy. It neither accentuates nor subdues color, a prime requirement when viewing press sheets and proofs since a wide range of colors can exist in an image.

D65 D65 IlluminantA light bluish colored light source used in color matching applications of paints, plastics,textiles, raw inks, and other manufactured products. D65 appears more neutral in balance to the eye even though the spectral graph does not correlate. D65 accentuates blue and subdues green and red.

D65 is the only daylight source that was actually measured. The other daylight sources were mathematically derived from these measurements. D65 is derived from the average of measurements made of light coming in a north facing window in the northern (European) hemisphere on an overcast day at various times through the day throughout the year.

D65 is also the reference illuminant used in sRGB and Adobe RGB (1998) color spaces. HDTV and SMPTE-C (SDTV) also use D65 as the reference white point.
