86-073 25 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=3 mm 975nm

The 86-073 is a high-performance longpass filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in optical systems that require a sharp cut-on wavelength, ensuring precise filtering capabilities. The filter boasts a 25 mm diameter, making it suitable for a wide range of applications, and a thickness of 3 mm, providing robustness and durability.

The 86-073 filter is constructed using UVFS Mal-1965 material, a high-quality substrate known for its excellent optical properties. The filter is coated on both the front and back surfaces with EDM 86-065, a hard coating that enhances the filter's durability and resistance to wear and tear, ensuring longevity and reliability in operation.

The longpass filter has a cut-on wavelength of 975 nm, meaning it allows transmission of wavelengths greater than this value while effectively blocking shorter wavelengths. This feature makes it ideal for applications where the detection or transmission of specific wavelength ranges is crucial.

The filter's geometry is designed in a thin lens shape, which not only contributes to its robustness but also allows for easy integration into various optical systems. The 86-073 filter is currently in stock and available for immediate use, as indicated by its valid weblink status.
