Standard diffusor
A standard diffusor is available to extend the measuring possibilities of spectraval 1501 and 1511 to spectral Irradiance. The calibration data of the diffusor will be stored in the device. The following parameters will be reached:
| Measuring range Illuminance | 2 - 1 250 000 lx (Illuminant A) 1 - 1 000 000 lx (typical white LED) |
| Illuminance accuracy | ± 2.4 % |
| Illuminance reproducibility | ± 5 % |
| Chromaticity accuracy | ± 0.002 xy (Illuminant A) |
| Color reproducibility | ± 0.0005 xy (Illuminant A) |
| Part number for spectraval 1501/1511 |
Part number for spectraval 1501NIR/1511NIR |
| ACC 032 | ACC 032NIR |
