China Manufacturer Optical Glass Filter Neutral Density Filter for Camera Lens

Manufacturer Optical Glass Filter Neutral Density Filter for Camera Lens
Product description
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.
