This is the 14NDF-80-1, a 12.7 mm diameter unmounted absorptive neutral density filter, sourced from the reputable vendor Standa. The filter is designed for use within the wavelength range of 400-700nm, offering an optical density (OD) of 0.1.
The filter is of the Neutral Density type, which means it reduces the intensity of light equally across the entire visible spectrum without altering its color balance. This makes it an ideal component for applications requiring light intensity reduction, such as in photography, cinematography, or scientific research.
The filter is made from UVFS Mal-1965 material, a common choice for its excellent optical properties and durability. It features a thin lens shape, with a thickness of 3mm, providing a balance between robustness and compactness.
