67-788 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 870nm

The 67-788 is a Bandpass Interference Filter, meticulously crafted by Edmund Optics. This filter is designed with a circular shape, featuring a 12.5 mm diameter and a thickness of 5.9 mm, making it a versatile choice for various optical applications.

The filter is constructed with a unique material ID, UVFS MAL-1965, which contributes to its exceptional optical performance. It is specifically designed to operate at a central wavelength of 870 nm, with a full width at half maximum (FWHM) of 10 nm. This wavelength specification makes it suitable for applications that require precise filtering within this spectral range.

The 67-788 filter boasts a sophisticated coating on both the front and back surfaces, identified as EDM 67-788. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission, thereby improving the overall signal-to-noise ratio of the system.

The filter's geometry is shaped as a thin lens, which can be advantageous in applications where compactness and minimal optical path differences are crucial. The physical data of the filter indicates a cut-on wavelength of 865 nm and a cut-off wavelength of 875 nm, providing a narrow bandpass for optimal filtering.
