Photographic LensNeutral density Filter
The neutral density Neutral density filter uses the absorption or reflection characteristics of the material to attenuate the light intensity. After the light from the visible region to the near-infrared region passes through the neutral density filter, different waves attenuate in the same proportion, so that the optical elements maintain approximately equal light energy transmittance in the wide band.
UTE Optics is a professional filter manufacturer. It can customize and produce neutral density Neutral density filters with different wavelengths from near ultraviolet to near infrared according to the needs of customers.
