88-274 25 mm Dia. UV-NIR Metallic Based Neutral Density Filter; OD 1.5 190-1700nm

The 88-274 is a Neutral Density Filter with a 25 mm diameter, manufactured by Edmund Optics. This filter is designed for use in the ultraviolet (UV) and near-infrared (NIR) spectrum, with a wavelength of 588 nm. It is part of the UVFS MAL-1965 material family, which ensures high-quality performance and durability.

The filter features a thickness of 3 mm, making it suitable for a wide range of optical applications. It is coated on both the front and back with EDM 88-268, a specialized coating that enhances its performance in the UV and NIR spectrum. The filter's shape is that of a thin lens, which contributes to its versatility and ease of integration into optical systems.

The 88-274 filter has an Optical Density (OD) of 1.5, which means it reduces the intensity of light by a factor of 3.16. This makes it ideal for applications where light intensity needs to be controlled or reduced, such as in high-powered laser systems or in astronomy for observing bright celestial bodies.

The filter is currently in stock and available for purchase through the Edmund Optics website. It is a valuable addition to any optical system that requires UV or NIR filtration, offering reliable performance and high-quality construction.
