47-532 25 mm Dia. NIR Metallic Based Neutral Density Filter; OD 1.5 700-1100nm
The 47-532 is a 25 mm diameter Neutral Density Filter, specifically designed for use in the Near-Infrared (NIR) spectrum with a wavelength of 588 nm. This filter is manufactured by Edmund Optics, a leading provider of optical components. The filter is part of the UVFS MAL-1965 material family, ensuring high-quality performance and durability.
The filter is circular in shape and has a thickness of 3 mm, making it suitable for a wide range of optical applications. The front and back of the filter are coated with EDM 47-829, a specialized coating that enhances its performance in the NIR spectrum. The coating provides an Optical Density (OD) of 1.5, which is equivalent to a transmission of 3.16% in the 700-1100nm range.
The filter is designed in a Thin Lens shape, which minimizes optical aberrations and distortions, ensuring clear and accurate optical transmission. The filter is currently in stock and available for immediate purchase through the Edmund Optics website.
