SLR (single-lens-reflex) viewing system and flare-free optical 

system provide accurate measurements of subjects at a 

distance with virtually no influence from light outside the 

measurement area.

1° measurement angle allows measurements of subjects as 

small as ø14.4 mm (at a subject distance of 1014 mm); by 

using optional Close-Up Lenses, subjects as small as ø1.3 mm 

can be measured.

• Luminance and chromaticity of small light sources such as 

LEDs, miniature neon lamps, etc.

• Luminance and chromaticity of general light sources such 

as tungsten lamps, fluorescent lamps, etc.

• Luminance and chromaticity of traffic signals, airport 

guidance lights, emergency exit signs, etc.

• Color measurements of subjects which cannot be measured 

by contact methods, such as distant building walls, just-

painted surfaces.

• Luminance and chromaticity of projectors.
