86-075 25 mm Dia. High Performance OD 4.0 Longpass Filter; t=3 mm 1075nm

The 86-075 is a high-performance longpass filter, measuring 25 mm in diameter and 3 mm in thickness, sourced from the renowned optical vendor, Edmund Optics. This filter is designed to transmit light at wavelengths greater than or equal to 1075 nm, while effectively blocking shorter wavelengths, making it ideal for applications requiring infrared (IR) light filtration.

The filter boasts a circular shape and is constructed from UVFS Mal-1965 material, a common choice for optical components due to its excellent transmission properties and durability. The 86-075 features a high optical density (OD) of 4.0, ensuring effective suppression of unwanted wavelengths and maintaining high contrast in your optical system.

Both the front and back surfaces of the filter are coated with EDM 86-067, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The 86-075 is designed with a thin lens shape, minimizing its impact on the overall optical path length and reducing the likelihood of aberrations.

The 86-075 is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. With its impressive specifications and reliable performance, this high-performance longpass filter is an excellent choice for a wide range of IR-based optical applications.
