The 13-107 is a 25 mm diameter Neutral Density Filter, manufactured by Hoya and sourced from Edmund Optics. This filter is designed to reduce the intensity of light entering the optical system without altering its color composition. It features an Optical Density (OD) of 2, which corresponds to a 100x reduction in light intensity within the 425-675nm wavelength range.
The filter is made from UVFS material, identified as MAL-1965, and has a thickness of 2mm. It is coated on both sides with EDM 13-090, a coating type not specified in the data. The filter's geometry is defined by its 25mm diameter and thin lens shape, making it suitable for use in various optical systems.
This Neutral Density Filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its "Valid - in stock" weblink status. The catalog number for this item is 13-107.
