67-797 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 970nm
The 67-797 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its circular shape, with a diameter of 12.5 mm and a thickness of 5.9 mm, making it suitable for a wide range of optical applications.
The filter is specifically designed to operate at a central wavelength (CWL) of 970 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows light within a narrow band around 970 nm to pass through while blocking out other wavelengths, making it ideal for applications that require precise wavelength selection.
The cut-on and cut-off wavelengths are 965 nm and 975 nm, respectively, further emphasizing its narrowband transmission characteristics. The filter's coating, both on the front and back, is identified as 'edm 67-797', which plays a crucial role in its performance.
The filter's geometry and physical data suggest that it is a thin lens, indicating that it can also serve lens-like functions in optical systems. The catalog number, 67-797, along with the vendor information, is provided for easy reference and purchasing.
