| SLR spot colorimeter for measuring light-source and surface luminance and chromaticity |
| 1° |
| 85mm f/2.8 lens; SLR viewing system; flare factor less than 1.5% |
| 9° with 1° measurement area indication |
| 1014mm (40 in.) to infinity |
| 3 silicon photocells filtered to detect primary stimulus values for red, green, and blue light Spectral response Closely matches CIE 1931 Standard Observer curves |
| FAST: Sampling time: 0.1s, Time to display: 0.8 to 1.0s; SLOW: Sampling time: 0.4s, Time to display: 1.4 to 1.6s Luminance units: cd/m2or fL (switchable) |
| FAST: 0.01 to 299,000cd/m2(0.01 to 87,530fL); SLOW: 0.01 to 49,900cd/m2(0.01 to 14,500fL) |
| Luminance (Y): &plun;2% of reading &plun;1 di Chromaticity (x,y): &plun;0.004 (Illuminant A measured at ambient temperature of 18 to 28°C/64 to 82°F) |
| Luminance (Y): &plun;0.2% of reading &plun;1 di Chromaticity (x,y): FAST: Y 100cd/m2or above: &plun;0.001; 48.1 to 99.9cd/m2: &plun;0.002; Below 48.1cd/m2: Below measurement range SLOW: Y 25.0cd/m2or above: &plun;0.001; 12.0 to 24.9cd/m2: &plun;0.002; Below 12.0cd/m2: Below measurement range (Measurement subject: Illuminant A) |
