86-339 12.5 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 440nm
The 86-339 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for fluorescence applications, featuring a center wavelength (CWL) of 440nm and a 40nm bandwidth.
The filter is made from UVFS MAL-1965 material, a common choice in the industry due to its excellent optical properties. It has a thickness of 2mm, providing durability and stability in its placement within optical systems.
The 86-339 filter is hard coated on both the front and back surfaces with EDM 86-339, a coating that enhances its performance and longevity. This coating helps to reduce unwanted reflections and increases transmission, making it ideal for sensitive optical applications.
The filter's geometry is defined by a circular shape, a common choice due to its ease of integration into various optical systems. The cut-on wavelength is 417nm, and the cut-off wavelength is 463nm, providing a narrow and precise bandpass for the specified 440nm CWL.
This filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. The item data also provides a catalog number for easy reference and ordering.
