total internal reflection
Light that is reflected back from the edge of the medium it is traveling through. When light rays travel at an angle greater than the "critical" angle, which is determined by the medium, the light ...

Total Internal Reflection Fluorescence Microscopy
The DeltaVision OMX V4 enables Total Internal Reflection Fluorescence Microscopy (TIRF). This technique uses an evanescent wave to selectively excite fluorophores that are close to the coverslip. This ...

Critical angle and total internal reflection - Higher - CCEA
The angle of incidence when the angle of refraction is 90 o, and the ray changes from just refracting to total internal reflection, is called the critical angle. The diagram below shows the light ...

Critical angle and total internal reflection - Higher - CCEA
Name the process happening to the ray at the point X. There is no light emerging from the prism at Y. Name the process happening to the light at Y. How does the speed of light change, if at all ...

Total internal reflection fluorescence (TIRF)
The Wolfson Bioimaging Facility provides total internal reflection fluorescence microscopy (TIRF) with its multi-laser, dual-camera Olympus/Abbelight SAFe360 system which also offers single molecule ...
Scientists develop novel device to modulate polarization of THz waves
Terahertz (THz) waves, situated between the microwave and infrared regions of the electromagnetic spectrum, have drawn considerable attention over the past two decades.
