Neutral density attenuatio filters can attenuate light intensity by utilizing the absorption or reflection characteristics of matter. After passing through neutral density filters, the light from visible to near-infrared region will attenuate in the same proportion at different wavelengths, so that the optical elements can maintain approximately the same light energy transmittance in a wide band. Shenzhen Nano Macro photonics Technology (NMOT) is a professional manufacturer of neutral density filters, providing a variety of wavelengths from near ultraviolet to far infrared neutral density attenuation filters in different bands.
