67-862 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 950nm
The 67-862 is a Bandpass Filter, specifically designed with a circular base shape and mounted diameter of 25 mm. This filter is sourced from the reputable vendor, Edmund Optics, and boasts a thickness of 5.9 mm. The filter's primary function is to allow light transmission within a specific range of wavelengths, while blocking other wavelengths.
The 67-862 is designed to permit light transmission at a central wavelength (CWL) of 950 nm, with a full width at half maximum (FWHM) of 10 nm. This precise wavelength range is achieved through the filter's unique coating, which is applied to both the front and back surfaces. The coating used for this filter is EDM 67-795, a traditional coating that enhances the filter's performance and durability.
The physical data of the 67-862 further highlights its capabilities. The cut-on wavelength is 945 nm, and the cut-off wavelength is 955 nm. This means that the filter begins to transmit light at 945 nm and stops transmitting at 955 nm, effectively filtering out wavelengths outside this range.
The filter's geometry is another notable feature. With a diameter of 25 mm, it provides a substantial surface area for light transmission. The thickness of 5.9 mm, on the other hand, ensures structural integrity and rigidity.
