Standard diffusor
A standard diffusor is available to extend the measuring possibilities of specbos 1211-2 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 | ± 0.5 % |
| Chromaticity accuracy | ± 0.002 xy (Illuminant A) |
| Color reproducibility | ± 0.0005 xy (Illuminant A) |
| f2 | < 3% (class B) |
| f2 | < 4% (class C) for standard diffusor specbos 1211UV-2 |
| Aperture (diameter) | 7 mm / snow-white |
| Part number for specbos 1211-2 |
Part number for specbos 1211-UV-2 |
| ACC 013/1 | ACC 013UV |
