47-530 25 mm Dia. NIR Metallic Based Neutral Density Filter; OD 1 700-1100nm

The 47-530 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 the reputable optical vendor, Edmund Optics, and is available for purchase through their website. The filter's catalog number is 47-530, and it is currently in stock.

This filter is designed with a circular base shape and a thin lens geometry, making it ideal for a wide range of optical applications. The filter has a diameter of 25 mm and a thickness of 3 mm, providing a compact yet robust design. The material ID for this filter is UVFS MAL-1965, indicating its specific composition and properties.

The 47-530 filter features a Neutral Density coating on both the front and back surfaces. This coating, identified as EDM 47-827, is a metallic-based coating designed to provide a uniform attenuation of light across the NIR spectrum. The Optical Density (OD) of this filter is 1, which corresponds to a transmission of approximately 10%. This makes it ideal for applications where a significant reduction in light intensity is required.
