WebJul 7, 2024 · The working principle of Interferometry technology consists on a splitting of the light into two beams that travel different optical paths and are then combined to produce interference. Interferometric objectives allow the microscope to operate as interferometer; fringes are observed in the sample when it is in focus. WebBio-Layer Interferometry (BLI) is a label-free technology for measuring biomolecular interactions. It is an optical analytical technique that analyzes the interference pattern of white light reflected from two surfaces: a layer of immobilized protein on the biosensor tip, and an internal reference layer. how to set parental controls on iphone 5 https://southcityprep.org
