86-995 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 640nm

The 86-995 is a Bandpass Filter, specifically designed for Fluorescence applications, available from Edmund Optics. This filter, with a diameter of 50 mm and a thickness of 2 mm, is a circular component made of UVFS Mal-1965 material. The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths.

The 86-995 filter is designed to pass light in the 640nm wavelength range, with a cut-on wavelength of 630nm and a cut-off wavelength of 650nm. This precise wavelength selection is crucial in many applications, including fluorescence microscopy, where specific wavelengths are used to excite and detect fluorescent molecules.

The filter features hard coating on both the front and back surfaces, identified as EDM 86-979. This coating enhances the filter's durability and resistance to wear, making it suitable for demanding environments. The filter's shape is described as a Thin Lens, indicating a precise curvature designed to control the path of light.
