47-209 25 mm Dia. UV-VIS Metallic Based Neutral Density Filter; OD 1.5 250-700nm

The 47-209 Neutral Density Filter is a circular filter with a 25 mm diameter and a thickness of 3 mm, sourced from the reputable vendor, Edmund Optics. This filter is designed for use in the ultraviolet and visible light spectrum, specifically between 250-700nm, making it suitable for a wide range of optical applications.

The filter boasts a neutral density of 1.5, which is achieved through a specialized metallic coating on both the front and back surfaces. This coating, identified as EDM 48-622, ensures consistent attenuation of light across the entire spectrum, resulting in a uniform optical density. The metallic coating also provides excellent durability and resistance to environmental factors, ensuring the filter maintains its performance over time.

The filter's thin lens shape allows for easy integration into optical systems, while its 25 mm diameter provides a generous aperture for maximum light capture. The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
