65-792 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 1500nm

The 65-792 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in optical systems that demand high-performance spectral filtering. The filter's primary function is to transmit light within a specific wavelength range while blocking light outside this range, making it ideal for applications that require precise wavelength selection.

The filter's central wavelength (CWL) is 1500nm, with a full width at half maximum (FWHM) of 12nm. This means it allows the transmission of light most efficiently around the 1500nm wavelength, with a tolerance of +/- 6nm. The filter's cut-on wavelength is 1494nm, and the cut-off wavelength is 1506nm, further illustrating its narrowband transmission characteristics.

The 65-792 filter is constructed with a base shape of a circle, ensuring easy integration into various optical systems. It has a thickness of 7.5mm, providing sufficient mechanical strength for handling and mounting. The filter material is UVFS Mal-1965, a type known for its excellent optical properties and durability.

The filter's front and back surfaces are coated with EDM 65-778, a traditional coating that enhances the filter's performance by reducing surface reflections and improving transmission. The filter's shape is a thin lens, further optimizing its performance in optical systems by minimizing optical aberrations.
