Absorptive Neutral Density Filter Mounted (Visible) / MAN
We offer a complete line of ND filters to reduce intensity of the visible light. This is an absorptive type of filter that reduces stray reflected light and reduces intensity of the light with minimal difference of transmission for visible wavelengths.
The transmittance can be fine tuned and can offer light intensity adjustment. Moreover, with a multi-filter set up, ultra fine light intensity tuning can be realized. The mounted filter (model MAN/MANY) with it’s outer frame can be easily mounted in our filter holder (model FH). For a filter with diameter 30mm outer frame please see lens holder (model LHF-30S) for your reference.
