C-Mount Neutral Density (ND) Filters

Laser Beam Attenuation with Stackable Bulk Absorption Filtration
 
Description: 

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 and also can
be combined with beam splitters.
They are set at a small wedge angle in the housing so as not to
cause interference effects.
