67-745 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 270nm
The 67-745 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 3.5 mm, making it suitable for a wide range of optical applications.
The filter is made from UVFS MAL-1965, a material specifically chosen for its optical properties. It is designed to operate at a central wavelength of 270nm, with a full width at half maximum (FWHM) of 10nm. The cut-on wavelength is 265nm, and the cut-off wavelength is 275nm, providing a narrow, precise bandpass.
The 67-745 features a thin lens shape, which is beneficial for applications where space is limited or precise alignment is required. The filter is coated on both the front and back surfaces with EDM 67-745, a proprietary coating developed by Edmund Optics to enhance its performance and durability.
