This is the 14NDF-60-1, 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 0.2.
The filter is of the Neutral Density type, which means it reduces the intensity of light without altering its color composition. This is particularly useful in various applications where controlling light intensity is crucial, such as in photography, cinematography, and scientific research.
The filter is made from UVFS Mal-1965 material, a common choice for its excellent optical properties. It features a thin lens shape, with a thickness of 3mm, making it suitable for use in systems where space is a constraint.
The front and back of the filter are coated with Sta 14ndf-0.2, a specialized coating that enhances the filter's performance and durability. The circular geometry of the filter, with a diameter of 12.7mm, adds to its versatility, making it compatible with a wide range of optical systems.
