90° diffusor

alternatively with filter

The standard diffusor of specbos 1211-2 and spectraval 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.

It is available in different versions for specbos 1211-2 and specbos 1211UV-2 as well.
