90° diffusor

with and without integrated OD filter for VIS/NIR/UV
Article number: ACC 012, ACC 012UV, ACC 032/90°
Device: specbos 2501, specbos 1211-2, spectraval 1511, spectraval 1501
The standard diffusor of specbos 2501, specbos 1211-2, spectraval 1501 and spectraval 1511 allows Irradiance measurements in axis to the device. There exist applications where this restricted set up cannot be used, e.g. if it is necessary to measure the Irradiance near a certain surface. The 90° diffusor allows to measure perpendicular to the instrument.

The 90° diffusor is available in different versions for all JETI spectroradiometers.

90° diffusor: f2 < 3 % (class B)
