#Reference #Vendors by Keit Spectrometers https://keit.co.uk ## traditional FTIR vs IRmadillo > Moving mirrors need a very precise alignment on a track, and any vibration of the their enclosure can cause noise in a spectrum or even no spectrum at all. The static optics inside the IRmadillo are free to vibrate because they all move together – meaning no loss in spectrum. ![[michelson-drawing-figure-1-png-e1600684428907-500x356.jpg|grid]] ![[sagnac-drawing-figure-2-png-15ju20-550x350.jpg|grid]] ### Left - traditional - Michelson interferemetor Based on a pair of moving mirrors and thus sensitive to vibration - creates **an interferogram with respect to time** as the mirrors move ### Right - IRmadillo - Sagnac interferometer uses a pair of stationary mirrors to reflect light in two opposite directions - light is focused onto the detector to create an interferogram **with respect to space** > The fundamental Sagnac loop has existed for almost as long as the Michelson interferometer, but it wasn’t practical for instruments until Keit’s novel mirror design was developed, as well as the development of infrared detectors with high enough resolution and throughput for spectroscopy. The IRmadillo has a solid probe instead of a fiber probe --- ## Use case flow chart ![[Infographic-when-to-decide-on-IRmadillo-final-409x1024-1.png]] Example of clear [[Visual Device|visual communication]] - conveys the same information as the table, but in a format that quickly guides customers to what they [[Need to know and need to share|Need to know]]. ## Comparison of process analytical techniques ![[Keit-IRmadillo-Table-Tech-comparison-1024x724.png]] ![[FTIR fingerprint regions#FTIR fingerprint regions]] ## User Manual snapshots more [[Visual Device|visual communication]] ### System Overview ![[Screen Shot 2022-01-22 at 1.43.02 PM.jpg]] ### Maintenance procedure ![[Screen Shot 2022-01-22 at 1.45.43 PM.jpg]]
