67-741 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 254nm
The 67-741 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 constructed using UVFS MAL-1965 as its primary material, ensuring durability and high-performance characteristics. It is designed to operate at a central wavelength of 254 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity makes it ideal for applications that require precise wavelength selection and narrow bandpass filtering.
The 67-741 features a front and back coating of EDM 67-741, which enhances its optical performance by reducing unwanted reflections and increasing transmission. The filter's geometry is shaped as a thin lens, further optimizing its performance in optical systems.
The filter's physical data includes a cut-on wavelength of 249 nm and a cut-off wavelength of 259 nm, providing a clear understanding of its operational spectrum. This information, along with the catalog number and vendor details, can be found on the Edmund Optics website, where the filter is listed as being in stock.
