This is a Profoto Replacement Diffusion Filter . The 15.75 x 15.75″ (40 x 40 cm) filter slides into the Profoto Zoom Reflector Filter Cassette (#505-524), which in turn slides into the Profoto Grid and Filter Holder for the Zoom Reflector (#505-523) — both available separately.
This diffuser will slightly soften the light ouput of your Profoto flash head. The degree of softening will be determined by the position ofthe zoom reflector in relationship to the flashtube.
