Chroma Technology … WebReflective Neutral Density. Filters. Reflective Neutral Density Filters attenuate the light beam by a combination of reflection and absorption. Holmarc’s reflective neutral density filters are made from BK7 or equivalent glass substrate with hard Inconel coating and are used to attenuate the intensity over a broad spectral region (350 - 1100 nm).
WebNeutral Density (ND) filters reduce the intensity of all wavelengths, or colors, of light equally from entering the camera, in measured amounts. This allows the photographer more control in selecting shutter speed and aperture combinations in a variety of conditions.
WebAndover's absorbing ND filters are unique in that they are AR coated to reduce surface reflections. Polished to TWF 1/4 wave or better, this enables them to be stacked without concern about losses and artifacts due to multiple reflections. Absorbing ND filters are perfect for imaging applications. Please note that all of our Absorbing ND ... WebNeutral density filters are ideal for controlling the intensity of illumination in the optical microscope, where they are commonly employed in brightfield, differential interference contrast, and fluorescence illumination (in which …
WebMay 8, 2014 · Short answer: A neutral density attenuator. Meaning? Long (er) answer: A filter that attenuates all wavelengths equally. Well, that’s an ideal ND filter, anyway. A real one affects different wavelength differently, but the difference is kept to a minimum.
