13-116 50 mm Dia. Hoya ND-40 Absorptive Neutral Density Filter; OD 0.4 425-675nm
The 13-116 is a 50 mm diameter Neutral Density Filter, manufactured by Hoya, and available through Edmund Optics. This absorptive filter is designed for use within the visible spectrum, specifically between 425-675nm, with an Optical Density (OD) of 0.4.
The filter boasts a circular shape, made from UVFS material with the catalog number MAL-1965. It features a thin lens design, with a thickness of 2.5mm, making it an ideal choice for applications where space is a constraint. The front and back surfaces of the filter are coated with EDM 13-099, a coating type known for its durability and optical performance.
This filter is particularly useful in applications where a reduction in light intensity is required without altering the color balance. It's ideal for photography, cinematography, and scientific research where consistent light conditions are crucial.
