67-778 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 770nm
The 67-778 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 770 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 765 nm, and the cut-off wavelength is 775 nm, ensuring a high level of transmission within the passband and a sharp roll-off outside of it.
The 67-778 filter features a thin lens shape, which allows for easy integration into optical systems. It is coated on both the front and back sides with the EDM 67-778 coating, providing excellent optical performance and durability.
