88-273 25 mm Dia. UV-NIR Metallic Based Neutral Density Filter; OD 1.3 190-1700nm
The 88-273 is a Neutral Density Filter with a 25 mm diameter and a thickness of 3 mm, designed for use in the ultraviolet (UV) and near-infrared (NIR) spectrum. This filter is manufactured by Edmund Optics, a leading provider of optical components.
The filter features a Metallic Based Neutral Density coating on both the front and back surfaces, denoted as 'edm 88-267'. This coating provides an Optical Density (OD) of 1.3, which corresponds to a transmission of approximately 5% across the entire UV-NIR spectrum (190-1700nm). This makes the filter ideal for applications requiring significant light reduction, such as high-intensity laser applications or high-dynamic-range imaging.
The filter is designed in a Thin Lens shape, which minimizes optical aberrations and ensures high-quality imaging. The catalog number for this filter is 88-273, and it can be found on the Edmund Optics website, where it is currently in stock.
