Neutral density filters

The measuring ranges of specbos 1211-2 and spectraval 1501 / 1511 for Luminance mode measurements are given in the datasheets. The ranges can be shifted to higher values using external attenuation filters, mounted in a cap to be attached to the instrument.

The filters for specbos 1211-2 and specbos 1211UV-2 have different housings (see the right picture).
