The combination of holes-pattern attenuating filter with a variable aperture is suitable when the light intensity of an integrating sphere light source should be adjustable within a large dynamic range at constant color temperature. The holes pattern attenuation filters are used to change the intensity levels in steps. The holes-pattern attenuation filter is changed using the filter wheel in the beam path between the light source and integrating sphere. The FW-170-6×2 can accommodate a total of up to six filters each with a 50mm diameter. RS232 interface.
