47-205 25 mm Dia. UV-VIS Metallic Based Neutral Density Filter; OD 0.3 250-700nm
The 47-205 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, with a wavelength of 588 nm.
The filter is made from a metallic-based material, specifically UVFS Mal-1965, which is known for its durability and stability in various optical applications. It features a neutral density of 0.3, which is equivalent to a 1/3 attenuation, making it suitable for applications requiring light reduction without altering the color balance.
The filter's coating is another notable feature. Both the front and back surfaces are coated with EDM 48-618, a coating that enhances the filter's performance and longevity. This coating helps to reduce reflections and increase transmission, making it an ideal choice for applications requiring high-quality optical performance.
The filter's thin lens shape allows for easy integration into various optical systems. It is currently in stock and available for purchase through the provided weblink.
