86-972 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 975nm
The 86-972 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow passband. Sourced from Edmund Optics, this filter features a circular shape with a diameter of 50 mm and a thickness of 3.5 mm, making it suitable for a wide range of applications.
The filter is designed to transmit light within a specific wavelength range, in this case, 975 nm, while blocking light at other wavelengths. The cut-on wavelength is 950 nm, and the cut-off wavelength is 1000 nm, providing a 50 nm passband. This precise wavelength selection is crucial in many applications, such as fluorescence microscopy, spectroscopy, and laser systems.
The filter is made from UVFS Mal-1965 material, a common choice for its excellent optical properties. The front and back surfaces of the filter are coated with EDM 86-948, a hard coating that enhances the filter's durability and resistance to scratches and environmental factors.
The filter's thin lens shape allows for easy integration into optical systems. It is currently in stock and available for immediate purchase, as indicated by its valid weblink status. For more information, users can visit the provided weblink.
