Product Description
What is neutral density filter?
The neutral density filter uses the absorption or reflection characteristics of light to attenuate the light intensity. After the light in the visible region to the near-infrared region passes through the neutral density filter, different wavelengths are attenuated in the same proportion. Make the optical element maintain approximately equal light energy transmittance in a wide wavelength band.
