The 67-864 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 970nm, with a full width at half maximum (FWHM) of 10nm, making it ideal for applications that require narrowband transmission. The filter features a thin lens shape, ensuring minimal optical aberrations and distortions.
The filter's physical dimensions include a diameter of 25mm and a thickness of 5.9mm, providing a robust and compact design suitable for various optical systems. The cut-on wavelength is 965nm, and the cut-off wavelength is 975nm, further enhancing its narrowband transmission properties.
The 67-864 filter is coated with EDM 67-797 on both the front and back surfaces, ensuring high transmission and low reflection across the passband. This coating also provides excellent environmental stability, making the filter suitable for use in various conditions.
