Fraunhofer Institute for Building Physics
Spectroradiometer
| Measurement | Spectrum of emitted radiation from light sources, transmission, absorption and reflection, evaluation of solar simulation equipment, spectral analysis of daylight, integral and wavelength-dependent irradiance |
| Standards | Additional/special procedure for DIN EN 410, generation of spectral match reports for measuring class, performance as per IEC 60904, ASTM E 927, colorimetry CIE1931 and CIE 1964 |
| Measurement object | Light sources of any type, solar simulation facilities, glazing façades, roof and wall building components |
Technical data
| Test specimen dimensions | Any dimensions |
| Integration time | 5 to 10 s |
| Resolution | Wavelength-dependent 1 to 10 nm |
| Viewing angle | 150° |
| Installation of the specimens | Wall to roof (0 to 90° continously variable) |
Special features
| Building dimensions | Due to the compact size, the spectroradiometer is portable and can be used locally during customer visits. A 3 m long glass fibre disconnects the sensor head from the spectrometer. Therefore measurement is independent on location and can be operated in narrow spaces. |
| Temperature range | Sensor head −30 to +70 °C, noncondensing |
| Intensity of irradiation | Integration can be done very fast on a wide variety of bandwidths within the measurement range |
| Calibration | Traceable to NIST |
