Neutral density filter
Strip gradient neutral density filters (abbreviated as stripe gradient density sheets) can attenuate light intensity by moving the filter or linear light source. They allow for precise adjustment of light energy along the length of the strip while maintaining a neutral spectral energy distribution, enabling the adjustment and control of light. There are metal alloy variable density sheets and low-reflective variable density sheets (GND). They can be applied to normal light as well as laser light sources. When two sheets are combined and moved in opposite directions, they can achieve significant attenuation of a large beam. The optional spectral range is from 250nm to 2500nm. Custom sizes, densities, and concentrations of sheet wavelengths can be tailored.
