65-654 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 647nm
The 65-654 is a Bandpass Filter by Edmund Optics, designed with a circular base shape and a diameter of 12.5 mm. This filter is specifically coated with EDM 65-654 on both the front and back surfaces, ensuring optimal performance. The filter's thickness measures 7.5 mm, making it suitable for various applications.
The 65-654 filter is designed to transmit light in the center wavelength (CWL) of 647 nm, with a full width at half maximum (FWHM) of 10 nm. The cut-on wavelength is 642 nm, and the cut-off wavelength is 652 nm, providing a narrow band of transmission. This filter is ideal for applications that require precise wavelength selection and high transmission.
The filter is mounted, making it easy to integrate into existing systems. It is currently in stock and available for purchase through the Edmund Optics website.
