The speckle is a scattering of light caused by micron-sized ridges and groves on an object’s surface.
This approach, which is being called micron-gap thermal photovoltaics (hence MTPV), is capable of generating 5-10 watts per square centimetre, a massive increase over what has been possible before.
All fixtures and gages are built to 2-5 micron accuracy in climate controlled shops?
Inductors were defined by electron-beam lithography and formed by depositing micron-thick aluminium metal onto the wafers.
If a glass layer's shape is off so much as a fraction of a micron, the scope's precision takes a mighty blow.
We offer 15 different grades of fabric with micron ratings of 1 to 115 microns.
And only this month it was discovered, by looking at the beads in an electron microscope, that they are chock full of diamonds a micron or less across.
Studies of ash captured from the air show that for every one of the largest particles (about 300 microns) there are a million or more in the 2 micron range.
每根硅线的长度在30至100微米(micron)之间,直径仅为1微米。
The Quad PD Array consists of either 10 -, 30 -, 40 -, or 50-micron diameter photodiodes.
They are available in premium grades from 0.1 to 45 micron.
The technology is producing cells that are often only two microns thick (a micron is one-millionth of a meter).
As a result, the makers have developed a generation of cells whose silicon layers are only a micron or two deep, as opposed to the usual thickness of 200-300 microns.
When these micron-sized lightfoils were immersed in water and hit with 130 milliwatts of light from the bottom of the chamber, they started to move up, as expected.
