87-884 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1575nm

The 87-884 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. The filter's primary function is to allow light transmission within a specific range of wavelengths while blocking light outside this range.

The 87-884 filter is designed to pass light in the 1575 nm wavelength, with a Cut-On wavelength of 1550 nm and a Cut-Off wavelength of 1600 nm. This precise wavelength selection is crucial in various applications, such as spectroscopy, biomedical imaging, and telecommunications.

The filter is made from UVFS Mal-1965 material, a common choice for its excellent optical properties and durability. The front and back surfaces of the filter are coated with EDM 87-858, a hard coating that enhances the filter's resistance to scratches and environmental damage, ensuring longevity and reliability in operation.

The filter's thin lens shape allows for easy integration into various optical systems. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
