47-531 25 mm Dia. NIR Metallic Based Neutral Density Filter; OD 1.3 700-1100nm
The 47-531 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 sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The filter is of the Circular type, made from UVFS material with the catalog number MAL-1965. It features a thin lens shape, ensuring minimal distortion and a compact design. The geometry of the filter includes a diameter of 25 mm and a thickness of 3 mm, making it suitable for a wide range of optical applications.
The 47-531 filter boasts a coating on both the front and back surfaces, specifically the EDM 47-828 coating. This coating is designed to enhance the filter's performance in the NIR spectrum, providing an Optical Density (OD) of 1.3 for wavelengths between 700 and 1100 nm. This makes it ideal for applications requiring precise control over NIR light intensity.
The filter's status is currently in stock, and more information, including pricing and detailed specifications, can be found on the Edmund Optics website at https://www.edmundoptics.com/p/13-od-25mm-dia-nir-nd-filter-/7612/.
