13-103 25 mm Hoya ND-13 Absorptive Neutral Density Filter; OD 0.9 425-675nm
The 13-103 is a 25 mm diameter Neutral Density Filter, manufactured by Hoya and sourced from Edmund Optics. This filter is designed for use in the visible spectrum, specifically between 425-675nm, making it suitable for a wide range of optical applications.
The filter features an Absorptive Neutral Density of 0.9, often denoted as ND-13, which reduces the light intensity by a factor of 3.16. This is achieved through a special coating, identified as EDM 13-086, applied to both the front and back surfaces of the filter. This coating ensures consistent light attenuation across the specified wavelength range.
The filter is shaped as a Thin Lens, with a thickness of 2.5mm, and has a circular geometry with a 25mm diameter. This compact design makes it compatible with various optical systems. The material ID for this filter is UVFS MAL-1965, although further details about the material are not provided in the item data.
The filter's catalog number is 13-103, and it can be found on the Edmund Optics website, where it is currently in stock. The weblink provided is valid, offering direct access to the product page for further information and purchasing options.
