47-528 25 mm Dia. NIR Metallic Based Neutral Density Filter; OD 0.3 700-1100nm

The 47-528 is a 25 mm diameter Neutral Density Filter, specifically designed for use in the Near-Infrared (NIR) spectrum with a wavelength of 588nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website. The filter is currently in stock, ensuring quick delivery for your optical project needs.

This filter is part of the Neutral Density Filter subtype, which is characterized by its ability to reduce the intensity of incident light without altering its color composition. This is particularly useful in applications where controlling light intensity is crucial, such as in high-powered laser systems or in photography where a specific depth of field is required.

The filter is circular in shape, with a diameter of 25mm and a thickness of 3mm, making it compatible with a wide range of optical systems. The front and back surfaces of the filter are coated with EDM 47-825, a metallic-based coating that enhances its performance in the NIR spectrum.

The filter is designed in a Thin Lens shape, which is a type of optical component that focuses light without introducing significant aberrations. This shape is particularly useful in applications where high optical quality is required, such as in imaging systems or interferometry.
