47-825 12.5 mm Dia. NIR Metallic Based Neutral Density Filter; OD 0.3 700-1100nm

The 47-825 is a Neutral Density Filter with a 12.5 mm diameter and a thickness of 1.5 mm, designed for use in the near-infrared spectrum. This filter is manufactured by Edmund Optics, a leading provider of optical components. The filter is part of the UVFS MAL-1965 material family, which is known for its high-quality performance in various optical applications.

The 47-825 filter features a front and back coating of EDM 47-825, which is specifically designed to provide optimal performance in the near-infrared range. The filter has an Optical Density (OD) of 0.3, which means it reduces the intensity of light by a factor of 2 (50% transmission). This makes it ideal for applications where a moderate reduction in light intensity is required.

The filter is designed to operate at a wavelength of 588 nm, which is in the middle of the near-infrared spectrum. This makes it suitable for use in a wide range of applications, including spectroscopy, imaging, and other optical systems that require light intensity reduction in the near-infrared range.

The 47-825 filter is available for purchase directly from the Edmund Optics website, and it is currently in stock. The filter is shipped in a Thin Lens shape, which is designed to minimize optical aberrations and provide the best possible performance.
