Multispectral
At neonsee, we face challenges of very special fields like the equipment testing for space missions. The increasing greenhouse gases concentration in our atmosphere, calls up space missions for earth observation. Those satellites carry e.g. radiometers to perform remote sensing (RS).
For remote sensing (RS) multispectral images are necessary where the spectrum of light is divided into many bands. Most earth observation satellites have three or more radiometers for remote sensing. Each radiometer obtains a digital image in a small spectral band. The bands are grouped into wavelength regions, depending on the origin of the light and the interests of the researchers.
neonsee solar simulation technology allows for analysis of several spectral frequencies at one time.
| Spectral properties | |
|---|---|
| Spectral range | 340-1800 nm is standard, others on request |
| Spectra | AM0, AM1.5G/D or customized |
| Irradiance range | 0.05 – 1.3 solar constants |
| Number of zones | 2-10 |
| Zonal wavelength ranges | Tailored to customer requirements |
| Spatial non-uniformity | ±2 % (Class A) |
| Filter wheel | Max. 2 filter wheels with 4 slots per wheel provide additional spectral & irradiance tuning possibilities |
| Calibration & Monitoring | |
| Zonal irradiance monitoring | Up to 8 exchangeable component cells provide a continuous measurement, used to monitor and re-adjust the irradiance of all spectral zones |
| Zonal irradiance calibration | An automated calibration routine both, lamp current as well as zonal irradiances, until the target currents of the component cells are reached |
| Calibration time expenditure | Setting a 5-zone simulator takes approx. 4 minutes |
| Calibration recipes | Calibration settings can be stored & re-called |
| General | |
| Energy efficiency | A system with 160×160 mm2 illuminated area requires a single 1500W lamp to generate an AM0 spectrum |
| System design | Modular and field upgradeable: additional zones and other components can be added in the field |
