86-943 12.5 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 725nm

The 86-943 is a Bandpass Filter with a diameter of 12.5 mm, manufactured by Edmund Optics. This filter is specifically designed for use in optical systems requiring a narrow bandwidth transmission, making it ideal for applications such as fluorescence microscopy, spectroscopy, and laser systems.

The filter features a center wavelength (CWL) of 725nm, with a cut-on wavelength of 700nm and a cut-off wavelength of 750nm. This precise wavelength selection is achieved through the use of hard coatings on both the front and back surfaces, denoted as 'edm 86-943'. These coatings are designed to enhance the filter's durability and performance, providing a consistent transmission across the specified bandwidth.

The filter has a thickness of 3.5 mm and is shaped as a thin lens. It is made from UVFS Mal-1965 material, which is known for its excellent optical properties and resistance to environmental factors. The filter's circular geometry allows for easy integration into various optical systems.
