88-279 50 mm Dia. UV-NIR Metallic Based Neutral Density Filter; OD 1.3 190-1700nm
The 88-279 is a Neutral Density Filter, specifically designed for use in the ultraviolet (UV) and near-infrared (NIR) spectrums. This filter, with a diameter of 50 mm and a thickness of 5 mm, is sourced from Edmund Optics, a leading provider of optical components.
The filter boasts a uniform optical density (OD) of 1.3, which is equivalent to a transmission of 10%, across the wavelength range of 190 to 1700 nanometers. This broad spectral coverage makes it suitable for a wide range of applications, including UV, visible, and NIR imaging and spectroscopy.
The 88-279 filter features a metallic-based coating, denoted as 'uvfs mal- 1965', on both the front and back surfaces. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission. The filter's thin lens shape further contributes to its performance, minimizing optical aberrations.
The filter's geometry and coating are designed to be compatible with a 'Thin Lens' system, ensuring easy integration into existing optical setups. The catalog number '88-279' and the web link provided (https://www.edmundoptics.com/p/13-od-50mm-dia-uv-nir-nd-filter/30537/) can be used for further reference or to check the current availability of the product.
