65-778 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 1500nm

The 65-778 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter features a circular geometry with a 12.5 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 1500 nm, with a full width at half maximum (FWHM) of 12 nm. The cut-on wavelength is 1494 nm, and the cut-off wavelength is 1506 nm, providing a narrow bandwidth that can help to reduce unwanted noise and improve signal clarity in your optical system.

The 65-778 filter is coated with a traditional coating on both the front and back surfaces. This coating helps to enhance the filter's performance by reducing reflections and improving transmission. The coating is identified as 'edm 65-778' on both surfaces.

The filter is mounted, which can help to simplify the integration process into your optical system. The mounting shape is a thin lens, which can provide additional flexibility in terms of system design and alignment.

The filter is currently in stock and available for purchase through the Edmund Optics website. The catalog number for this item is 65-778, and the web link provided is a direct link to the product page on the Edmund Optics website.
