Systems for Radiometric Measurements


Spectroradiometer specbos 1201 and specbos 1211

JETI offers two basic models of spectroradiometers based on line array spectrometers. specbos 1201 is an instrument for the visible range of spectrum. It can be used as luminance as well as as illuminance meter. Furthermore it is available for luminous flux measurement (specbos 1301) and for luminous intensity measurement (specbos 1401).
specbos 1211 is a broadband spectroradiometer and covers wavelengths from UV to NIR. It is available in a special UV version as well as for luminous flux measurement (specbos 1311). specbos 1211 is about 10 times more sensitive than specbos 1201.
The application notes 15 and 28 show a comparison of the devices.
