65-819 50 mm Dia. Hoya ND-0.3 Absorptive Neutral Density (OD 1.5) Color Filter
The 65-819 is a 50 mm diameter absorptive neutral density filter, manufactured by Hoya and distributed by Edmund Optics. This filter is designed to reduce the intensity of light entering the optical path without altering its color composition. The ND-0.3 designation indicates a 1.5 optical density (OD), which corresponds to a 50% transmission of light.
The filter features a circular geometry with a 1.5 mm thickness, making it suitable for a wide range of optical applications. It is coated with EDM 48-530 on both the front and back surfaces, which enhances its durability and optical performance. The wavelength of this filter is 588 nm, and it operates within the 400-700 nm spectral range.
This filter is categorized as a color glass type and is designed in a thin lens shape. It is currently in stock and available for purchase through the Edmund Optics website. The catalog number for this item is 65-819.
