The 88-571 is a Bandpass Filter, specifically designed with a 25 mm diameter and a thickness of 3.5 mm. This filter, sourced from Edmund Optics, is a crucial component for applications requiring precise wavelength selection.
The filter's primary function is to allow light in a specific wavelength range to pass through while blocking other wavelengths. In this case, the 88-571 is designed to pass light in the 680nm range, with a Cut-On wavelength of 675nm and a Cut-Off wavelength of 685nm. This makes it ideal for applications where a narrow band of light around 680nm is needed.
The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. The front and back of the filter are coated with EDM 88-568, a hard coating that enhances the filter's durability and resistance to wear and tear.
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.
