The 65-816 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 2.5 mm and operates within the wavelength range of 400-700nm.
The filter boasts a catalog number of 65-816 and is part of the Absorptive Neutral Density series, specifically the ND-13 variant, which corresponds to an optical density (OD) of 0.9. This OD value signifies a reduction of 1/3 of the light intensity, making it ideal for applications requiring light control.
The filter's front and back surfaces are coated with EDM 48-528, a coating type known for its durability and light transmission properties. The filter's shape is defined as a thin lens, and it is made from UVFS Mal-1965 material, a type often used in optical applications due to its specific properties.
