88-266 12.5 mm Dia. UV-NIR Metallic Based Neutral Density Filter; OD 1 190-1700nm

The 88-266 is a Neutral Density Filter with a 12.5 mm diameter, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed for use in the ultraviolet (UV) and near-infrared (NIR) spectrum, making it an ideal choice for applications that require broadband attenuation.

The filter boasts a Metallic Based Neutral Density coating on both the front and back surfaces, denoted as 'edm 88-266'. This coating is responsible for the filter's primary function: to reduce the intensity of incident light without altering its color composition. The coating's performance is consistent across the 190-1700nm wavelength range, providing an Optical Density (OD) of 1.

The filter's geometry is another notable feature. It has a thickness of 1.5 mm, which is relatively thin, reducing the likelihood of introducing unwanted optical path differences. The circular shape, a common form factor in optical components, ensures easy integration into various optical systems.

This filter is available in a Thin Lens configuration, which is beneficial for applications where space is at a premium or where maintaining a compact optical layout is crucial. The catalog number for this item is 88-266, and it can be found on the Edmund Optics website, where it is currently in stock.
