Neutral density (by absorption) filters «In Stock»
Neutral density (by absorption) filters are designed for a flat transmission over a particular wavelength range and defined by the optical density (OD). Overall optical attenuation is a sum of optical absorption in neutral density optical glass and Fresnel reflection losses. Neutral density optical filter densities add up when used in series.
