67-854 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 860nm
The 67-854 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 860nm, with a full width at half maximum (FWHM) of 10nm. The filter is mounted, providing convenience and ease of use for the end-user.
The filter's geometry is defined by a diameter of 25mm and a thickness of 5.9mm. The cut-on wavelength is 855nm, and the cut-off wavelength is 865nm, with a central wavelength (CWL) of 860nm. This specificity in wavelength makes the filter ideal for applications that require precise filtering within the near-infrared spectrum.
The coating on both the front and back of the filter is EDM 67-787, which is a traditional coating that enhances the filter's performance and durability. The filter's shape is that of a thin lens, further adding to its versatility and applicability in various optical systems.
