Since it was declared a Special Economic Zone, one of the focal spots of China's economic transformation, Shenzhen has drawn several million people.

To optimize the effectiveness of STED, the destructive interference in the center of the focal spot needs to be as close to perfect as possible.

The focal spot size is important in x-ray microprobe instrumentation where x-rays are focused onto a biological sample to investigate phenomena such as the bystander effect.
14.
Two principal factors play simultaneously : the apparent focal spot size and the ratio between object-film distance ( OFD ) and focus-film distance ( FFD ).

Researchers also suggest the possibility that these megalithic cemeteries could have been a focal spot of the cultural landscape and served the purpose of bringing people together.

Vulcan can deliver 500J on target in a compressed pulse of 500fs giving a peak irradiance of 10 21 W / cm 2 in a 5?m focal spot.
17.
For instance, a plano-convex lens, which is used to focus a collimated beam, produces a sharper focal spot when used with the convex side towards the beam source.
18.
Using an appropriate ring-like focal spot for the light that switches the molecules into the dark state, the fluorescence can be quenched at the outer part of the focal spot.

Fine focal spot sizes will minimise geometric unsharpness, and therefore give more detailed images, but it is often impossible to employ them due to the tube loading necessary in the exposure.
