| 1. | Adjusting the excitation conditions can rotate this focal spot around the pipes circumference.
|
| 2. | The point where the electron beam strikes the target is called the focal spot.
|
| 3. | Rates of 80 frames per second have been recorded, with focal spots around 60 nm.
|
| 4. | The focal spot has a size of roughly half a pixel size ( < 0.05?).
|
| 5. | However, the focal spot size is dependent on the intensity of the laser being used for depletion.
|
| 6. | Here the X-rays are focused to a point and the sample is mechanically scanned through the produced focal spot.
|
| 7. | Therefore, fluorescence only still takes place at the center of the microscope's focal spot and the spatial resolution is increased.
|
| 8. | The focal spot temperature can reach during an exposure, and the anode assembly can reach following a series of large exposures.
|
| 9. | STED functions by depleting fluorescence in specific regions of the sample while leaving a center focal spot active to emit fluorescence.
|
| 10. | LS in this case stands for LASER-servo, which uses a very low-power superluminescent LED that generates light with a small focal spot.
