The 13-160 is a Neutral Density Filter, specifically designed for use in the near-infrared spectrum, with a wavelength of 588nm. This filter is manufactured by Hoya, a renowned name in the optical industry, and is available through Edmund Optics. The catalog number for this product is 13-160.
The filter is circular in shape, with a diameter of 12.5mm and a thickness of 3mm, making it suitable for a wide range of optical applications. The front and back of the filter are coated with EDM 13-160, a specialized coating that enhances its performance and durability.
The 13-160 filter is an absorptive neutral density filter, meaning it reduces the intensity of light without altering its color balance. It has an optical density of 0.3, which corresponds to a transmission of approximately 50%. This makes it ideal for applications where light intensity needs to be controlled, such as in photography or scientific research.
The filter is designed to operate in the 600-1050nm range, making it suitable for use with near-infrared light sources. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status.
