C-Mount Neutral Density (ND) Filters
The individual filters come in three versions, the ND1 filter in the red housing with ~10% transmission in the visible, the ND2 filter in the black housing with ~1% transmission and the ND3 filter in the green housing with ~0.1% transmission. The individual filters can be screwed on top of each other and thus stacked. They are set at a small wedge angle in the housing so as not to cause interference effects.
