The 88-272 is a Neutral Density Filter with a 25 mm diameter, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed to provide a consistent attenuation across the ultraviolet (UV) and near-infrared (NIR) spectrum, making it an ideal choice for applications that require broadband light reduction.
The filter features a Metallic Based Neutral Density design, which ensures a uniform and predictable optical density (OD) of 1 across the 190-1700nm wavelength range. This broad attenuation range makes the 88-272 suitable for a wide variety of applications, including UV-VIS-NIR spectroscopy, laser applications, and imaging systems that operate across these wavelengths.
The 88-272 has a circular geometry, with a diameter of 25 mm and a thickness of 3 mm. This compact design ensures easy integration into various optical systems, while the thin lens shape minimizes unwanted optical path differences.
The filter's front and back surfaces are coated with the EDM 88-266 coating, which further enhances its performance in UV-NIR applications. This coating provides excellent environmental stability, ensuring the filter maintains its optical properties even under harsh conditions.
