67-819 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 310nm
The 67-819 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter features a circular shape with a 25 mm diameter and a thickness of 3.5 mm, making it suitable for various optical applications. The filter is made of UVFS material, specifically identified as MAL-1965, ensuring durability and reliability.
The 67-819 filter is designed to operate at a central wavelength of 310 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. The filter's cut-on wavelength is 305 nm, and the cut-off wavelength is 315 nm, further enhancing its wavelength specificity.
The filter is coated on both the front and back with EDM 67-752, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance and durability, ensuring optimal functionality in various conditions. The filter's shape is that of a thin lens, further expanding its potential applications in optical systems.
