65-816 50 mm Dia. Hoya ND-13 Absorptive Neutral Density (OD 0.9) Color Filter; t=2.5 mm 400-700nm
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.
This filter is currently in stock and can be purchased directly from the Edmund Optics website, with the provided weblink serving as a direct path to the product page. The filter's status as 'Valid - in stock' indicates its immediate availability for purchase and use.
