Seated in the filter wheel of the A8580 and A6780 cameras, this plastic spectral filter makes some thin-film plastics opaque so the camera measures the film rather than what lies behind it. It swaps in alongside the other factory-installed filters in the wheel. It suits laboratory and process imaging that must be separated by wavelength.
