65-696 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 508nm

The 65-696 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 7.5 mm, making it suitable for a wide range of optical applications.

The filter is designed to operate at a central wavelength (CWL) of 508 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity makes it ideal for applications that require a narrow bandwidth, such as fluorescence microscopy or laser spectroscopy.

The 65-696 filter is cut on at 503 nm and cut off at 513 nm, ensuring a high transmission rate within the specified bandwidth and a sharp roll-off outside of it. This results in a high-quality, high-contrast image, free from unwanted noise or signal.

The filter is coated on both the front and back surfaces with EDM 65-636, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.

The filter's thin lens shape allows for easy integration into existing optical systems, while its mounted design ensures stability and alignment, reducing the need for additional mounting hardware.
