Neutral density filters

The measuring range of specbos 1211-2 for Luminance mode measurements is given in the datasheet. It can be shifted to higher values by external attenuating filters, mounted in a cap to be attached to the instrument.

The filters for specbos 1211-2 and specbos 1211UV-2 have different housings.

spectraval 15x1 can measure up to 100 000 cd/m2 (typical white LED spectrum). It can be shifted to higher values by external attenuating filters, mounted in a cap to be attached to the instrument.
