65-786 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 1200nm
The 65-786 is a 25 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 7.5mm, specifically designed for a central wavelength of 1200nm. This filter is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The filter is of the bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. This particular model has a cut-on wavelength of 1195nm and a cut-off wavelength of 1205nm, with a central wavelength of 1200nm. The cut-on and cut-off wavelengths are crucial in determining the range of wavelengths that the filter will allow to pass through.
The 65-786 filter is made from UVFS Mal-1965 material, which is a common choice for optical filters due to its excellent optical properties. The filter is coated on both the front and back with EDM 65-772, a type of coating that enhances the filter's performance and durability.
The filter's geometry is that of a thin lens, with a diameter of 25mm and a thickness of 7.5mm. This thickness is crucial as it affects the filter's performance and should be considered when integrating it into an optical system.
