Neutral Gray Glass Filters

Neutral Gray Glass Filters

The neutral density filter can attenuate the light intensity by using the absorption or reflection characteristics of the material to the light. After passing through the neutral density filter, the light from the visible light region to the near-infrared light region attenuates in the same proportion at different wavelengths, so that the optical elements maintain approximately equal light energy transmittance in the wide band. Also known as neutral density filter, neutral filter, ND filter, attenuator, fixed density filter, etc.

UTE Optics is a professional neutral density filter supplier, providing more than 17 kinds of transmittance, optical density from od0-od4, wavelength from near ultraviolet to far infrared neutral attenuators in different bands. For product inventory information, welcome to inquire.
