Neutral density filter
Strip step gradient neutral density filter (also referred to as strip step density sheet) attenuates light intensity based on the discrete number of steps within the filter area. The light density within each discrete area is a fixed value. This filter can be applied in fields such as natural light and lasers. It includes metal alloy variable density sheets and low reflection variable density sheets (GND), with an optional spectral range of 250nm to 2500nm. Custom sizes, densities, and concentrations of sheet wavelengths can be tailored.
