87-791 25 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 625nm

The 87-791 is a Bandpass Filter, specifically designed by Edmund Optics with a 25 mm diameter and a 3.5 mm thickness. This filter is hard-coated, ensuring durability and longevity, and is designed to pass light within the 625nm wavelength range while blocking other wavelengths.

The filter's physical data includes a cut-on wavelength of 612.5nm and a cut-off wavelength of 637.5nm, with a center wavelength (CWL) of 625nm. This precise wavelength specification makes the 87-791 ideal for applications that require narrow-band light transmission.

The front and back of the filter are coated with EDM 87-779, a coating type known for its high-quality performance. The filter's shape is that of a thin lens, further enhancing its functionality and usability.

The 87-791 is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. For more information or to make a purchase, users can visit the provided weblink.
