84-116 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 572nm

The 84-116 is a Bandpass Filter, specifically designed for Fluorescence applications, available from Edmund Optics. This filter, with a catalog number 84-116, has a diameter of 50 mm and a thickness of 2 mm, making it a substantial yet manageable component for various optical setups.

The filter is designed to pass light within a specific range of wavelengths, centered around 572 nm. The cut-on wavelength is 555.5 nm, and the cut-off wavelength is 588.5 nm, providing a bandwidth of 28 nm. This precise wavelength selection is crucial in fluorescence applications, where specific light frequencies need to be isolated or emphasized.

The 84-116 filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent transmission characteristics and durability. The filter is coated on both sides with EDM 84-084, a hard coating that enhances the filter's longevity and resistance to wear and tear, making it suitable for demanding environments.

The filter's shape is that of a Thin Lens, which can be beneficial in certain optical configurations, providing minimal distortion and a wide field of view. The filter is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its weblink status.
