The 67-761 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 5.4 mm, making it suitable for various optical applications.
The filter is designed to operate at a central wavelength (CWL) of 370nm, with a full width at half maximum (FWHM) of 10nm. This specificity makes it ideal for applications that require precise wavelength selection and narrow bandwidth, such as fluorescence microscopy or spectroscopy.
The 67-761 features a cut-on wavelength of 365nm and a cut-off wavelength of 375nm. This means that it begins to transmit light at 365nm and stops transmitting at 375nm, effectively filtering out any wavelengths outside this range.
The filter is coated on both the front and back sides with Edmund Optics' proprietary coatings, denoted as EDM 67-761. These coatings enhance the filter's performance and durability, ensuring reliable and consistent operation.
The filter's shape is that of a thin lens, which allows for easy integration into optical systems. It is currently in stock and available for purchase through the provided weblink.
