65-817 50 mm Dia. Hoya ND-0.3 Absorptive Neutral Density (OD 1) Color Filter
The 65-817 is a 50 mm diameter absorptive neutral density (ND) color filter, manufactured by Hoya and distributed by Edmund Optics. This filter is designed with a thickness of 1 mm and offers a wavelength of 588 nm, making it suitable for a wide range of optical applications.
The filter boasts a catalog number of 65-817 and is available for purchase directly from the Edmund Optics website, where it is currently listed as in stock. The filter is part of the UVFS MAL-1965 material ID category, further attesting to its high-quality construction and performance capabilities.
The 65-817 filter features a circular base shape and a thin lens geometry, making it compatible with a wide range of optical systems. The front and back of the filter are coated with EDM 48-529, a coating that enhances the filter's durability and performance.
This filter is a color glass type, offering a neutral density of 0.3, or an optical density of 1. It is designed to absorb a specific portion of the light spectrum, reducing the overall intensity of the light passing through it. This makes it an ideal choice for applications where precise control over light intensity is required.
