basic information
Neutral density filters (abbreviated as ND filters) are filters that maintain a constant spectral energy distribution with attenuation. Fixed neutral density filters can provide uniform attenuation across a wide spectral range, coated with a durable metal film, and can be used in fields such as natural light and lasers. There are absorption-reflection type ND filters and low-reverse type ND filters, which attenuate light neutrally over a large spectral range and are specifically applicable to optical systems. Custom sizes, densities, and wavelengths of sheets can be tailored; please contact us for more details.
