88-269 12.5 mm Dia. UV-NIR Metallic Based Neutral Density Filter; OD 2 190-1700nm

The 88-269 is a Neutral Density Filter with a 12.5 mm diameter, sourced from the renowned optical components vendor, Edmund Optics. This filter is specifically 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 88-269'. This coating provides an Optical Density (OD) of 2, which translates to a transmission of approximately 1% across the entire UV-NIR spectrum (190-1700nm). This high attenuation level ensures consistent and reliable light reduction, regardless of the wavelength.

The filter's geometry is another notable feature. It has a thickness of 1.5 mm and a base shape of a circle, which is common for filters used in optical systems. The circular shape allows for easy integration into various optical setups. The filter is also designed as a Thin Lens, which helps minimize optical aberrations and distortions.

The catalog number for this filter is 88-269, and it is currently in stock. For more information or to make a purchase, users can visit the provided weblink: https://www.edmundoptics.com/p/20-od-125mm-dia-uv-nir-nd-filter/30527/.
