from UNI OPTICS(Fujian) Co., Ltd
A Neutral Density filter allows a photographer to control the exposure in an image very easily. The filter stops light reaching the camera sensor, therefore allowing us to leave the camera with a higher aperture for a longer amount of time. [See More]

from Foctek Photonics, Inc.
Neutral density filters attenuate, split or combine beams in a range of irradiance ratios with little dependence on wavelength. FOCtek offers two kinds of neutral density filters, which are neutral grey glass type filters and metallic coated type filters made of optical glass such as N-BK7, H-K9L... [See More]

from Andover Corporation
Metallic-coated infrared neutral density filters (IR ND filters) obtain their optical density from a metal alloy coating on a substrate determined by the wavelength region of interest. Unlike the all-dielectric or absorption type, the metallic type ND filter employs a combination of absorption and... [See More]

from Andover Corporation
With their ability to minimize back-reflections and scattered light, absorptive neutral density (ND) filters are ideal for calibration. In contrast to the metallic type, absorption-type filters achieve their optical density by absorbing light within the substrate. For this reason, thickness is a key... [See More]
