Absorptive Neutral Density Filter Unmounted (Visible) / AND-C
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.
