65-721 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 730nm
The 65-721 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 730 nm, with a full width at half maximum (FWHM) of 10 nm, making it ideal for applications that require narrowband transmission.
The filter is constructed with a thickness of 7.5 mm, providing durability and stability. It features a traditional coating on both the front and back surfaces, denoted as EDM 65-661. This coating enhances the filter's performance and longevity.
The 65-721 filter has a cut-on wavelength of 725 nm and a cut-off wavelength of 735 nm, as indicated in its physical data. This ensures a tight transmission band, which is crucial for many optical systems.
The filter is shaped as a thin lens, allowing for easy integration into various optical setups. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status.
