The 13-155 is a Neutral Density Filter, specifically designed for use in the near-infrared spectrum, with a wavelength of 588nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and boasts a catalog number of 13-155. The filter is circular in shape, with a diameter of 12.5mm and a thickness of 1mm, making it a compact yet effective optical component.
The 13-155 filter features a unique absorptive coating, denoted as 'edm 13-155' on both the front and back surfaces. This coating is designed to provide a neutral density of 0.3, or an optical density of 1, within the specified wavelength range. This means that the filter reduces the intensity of incident light by a factor of 10, making it an ideal tool for managing light levels in high-intensity applications.
The filter is designed with a 'Thin Lens' shape, which suggests that it has been optimized for use in optical systems where minimal thickness and weight are desirable.
