TECHSPEC® UV-NIR Neutral Density Filters Provide Constant Transmission from 190-1700nm

2/24/2014, Barrington, NJ USA   —

Edmund Optics® (EO), the premier provider of optical components, introduces new TECHSPEC® UV-NIR Neutral Density (ND) Filters. These versatile filters are used to attenuate light from the ultraviolet (UV) to the near-infrared (NIR) for use in a wide variety of applications.

ND Filters feature outstanding surface characteristics

TECHSPEC UV-NIR Neutral Density Filters exhibit excellent parallelism of less than 5 arcseconds with outstanding surface characteristics. They provide constant, ultra-broadband performance from 190-1700nm. A UV-NIR Neutral Density Filter Kit, available in 12.5, 25 and 50mm diameter sizes, includes all optical densities for maximum versatility and utility.

Stack filters to create intermediate density values

TECHSPEC UV-NIR Neutral Density Filters are ideally suited for a wide range of applications, including spectroscopy, machine vision, or ellipsometry. They are also excellent for use with low power lasers. TECHSPEC UV-NIR Neutral Density Filters can be stacked to create intermediate density values for optimal value and ease of use.

Available 18 varieties and three complete filter kits

In addition to the ND Filter Kits, TECHSPEC UV-NIR Neutral Density Filters are available in 18 different individual models, with diameters of 12.5mm, 25mm and 50mm and optical densities of 0.3, 0.5, 1.0, 1.3, 1.5 and 2.0.

Range of substrates for UV, visible, or IR applications. Absorptive, reflective, continuously variable, or stepped versions available.

Learn how to calculate transmission or optical density of ND filters with two simple equations.
