for lower Irradiance
A diffusor with increased transmission has a higher error in cosine matching, but there exist applications where this can be tolerated. One example is the measurement of point like sources as vehicle lamps in a longer distance. Therefore, two modified diffusors are offered as accessory for specbos 1211-2 and spectraval 15x1 - a version with medium transmission and a version with high transmission:
The transmission of the medium version is 20 times higher and the transmission of the high version is 60 times higher than that of the standard diffusor version.

If you want to order such diffusor for a device, which was manufactured before 2019, please add the serial number and the desired measuring range to your request.
