... By "optical pumping", we mean the use of light to change the population of a set of energy levels of a system from the Boltzman distribution at the temperature of the experiment. That is, a system of atomic spin orientations is "pumped" from an equilibrium distribution over magnetic sub-states into ...

... Cambridge, England). The bead was scanned 1.5 pm along the optical axis and 0.8 pm in lateral direction. The smallest resolvable step of the stage was 10 nm, thus providing a high-precision measurement of the PSF. The confocal resolution was determined by using the 4Pi-confocal arrangement with the ...

Multimode or Single-Mode Optical Fiber
... Multimode and Single-Mode – What’s the Difference? The way in which these two fiber types transmit light eventually led to their separate names. Generally designed for systems of moderate to long distance (e.g., metro, access and long-haul networks), single-mode optical fibers have a small core size ...

To understand the basics of reflection and refraction
... • A surface is defined to be a point where the index of refraction changes. • The most common form of this is when you have 2 different types of materials – such as air, glass, water, ect. • For each the speed of light is different. • When the light enters the material the speed changes but the rest ...
