The 88-267 is a Neutral Density Filter with a 12.5 mm diameter, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use in the ultraviolet (UV) and near-infrared (NIR) spectrum, making it an ideal choice for applications that require broadband light attenuation in these regions.
The filter boasts a Metallic Based Neutral Density coating on both the front and back surfaces, denoted as 'edm 88-267'. This coating is responsible for the filter's primary function: reducing the intensity of incident light while maintaining a neutral color balance. The Optical Density (OD) of this filter is 1.3, which translates to a transmission of approximately 5% over the entire UV-NIR spectral range (190-1700nm).
In terms of physical geometry, the filter has a thickness of 1.5mm and a base shape of a circle. It is designed to fit Thin Lens configurations.
