The 65-697 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 510nm, with a full width at half maximum (FWHM) of 10nm, making it ideal for applications that require narrowband transmission.
The filter features a circular geometry, with a thickness of 7.5mm, providing robustness and durability. It is cut on at 505nm and cut off at 515nm, ensuring a tight control over the spectral range. The center wavelength (CWL) of the filter is 510nm, providing a precise and accurate transmission window.
The 65-697 is coated with EDM 65-637 on both the front and back surfaces, enhancing its performance and longevity. This coating provides excellent environmental stability, making the filter suitable for use in various conditions.
The filter is designed in a thin lens shape, allowing for easy integration into optical systems. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
