Neutral density filter
The circular step neutral density filter (abbreviated as circular step density sheet) attenuates the intensity of light 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. The outer diameter of the filter can be selected from 25 mm to 100 mm. The optional usable spectral range is from 250 nm to 2500 nm. Special sizes, densities, and concentrations of sheet wavelengths can be customized.
