67-789 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 890nm

The 67-789 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 designed to operate at a central wavelength of 890 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity makes it ideal for applications that require a narrow bandwidth, such as fluorescence microscopy or laser spectroscopy. The cut-on wavelength is 885 nm, and the cut-off wavelength is 895 nm, ensuring a high level of transmission within the passband and a sharp roll-off outside of it.

The 67-789 filter features a thin lens shape, which can be beneficial in applications where space is limited or precise alignment is required. The front and back surfaces of the filter are coated with the EDM 67-789 coating, which provides excellent optical performance and durability.

This filter is currently in stock and available for purchase through the Edmund Optics website.
