65-718 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 676nm
The 65-718 is a 25 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 7.5 mm, designed for use in optical systems where a narrow bandwidth transmission is required. This filter is sourced from Edmund Optics and is available for purchase directly from their website, with the current status indicating it is in stock.
The filter is designed to transmit light in the center wavelength (CWL) of 676 nm, with a full width at half maximum (FWHM) of 10 nm. This means that the filter will allow light to pass through if its wavelength falls within the range of 671 nm to 681 nm, with the highest transmission occurring at 676 nm. This makes it ideal for applications where a specific wavelength needs to be isolated or emphasized.
The filter is constructed from UVFS Mal-1965 material, and features a thin lens shape. It is coated on both the front and back surfaces with EDM 65-658, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing reflections and increasing transmission, thereby improving the overall efficiency of the optical system.
In terms of physical dimensions, the filter has a diameter of 25 mm and a thickness of 7.5 mm. This makes it suitable for use in a wide range of optical systems, from compact portable devices to large-scale laboratory setups. The filter is mounted, providing a convenient and secure method of integration into an optical system.
