88-268 12.5 mm Dia. UV-NIR Metallic Based Neutral Density Filter; OD 1.5 190-1700nm

The 88-268 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 high optical density (OD) of 1.5, which translates to a transmission of approximately 3.16% across the entire UV-NIR spectrum (190-1700nm). This makes it highly effective in reducing the intensity of incident light, thereby preventing overexposure and potential damage to sensitive optical components.

The 88-268 features a metallic-based coating on both the front and back surfaces, denoted as 'edm 88-268'. This coating is designed to ensure consistent attenuation across the UV-NIR spectrum, providing a uniform and predictable optical response.

The filter has a thin lens shape, with a thickness of 1.5mm, making it suitable for use in compact optical systems where space is at a premium. The circular geometry of the filter, with a diameter of 12.5mm, allows for easy integration into various optical setups.
