How Optics Science changed(ing) the world

It would be hard to imagine the world we live in today without microchips. They are a core that enables our technology to function.
Everything from our smartphones and laptops to spaceships and med technology requires to use of a microchip to compute and to err less throughout the zillions of operations. 

But how this super tiny technology is made?

To give you a short answer - optics.
The well-known German company Zeiss is the world's biggest optic lens supplier. Its logistical chain covers all types of niches including medicine, military tech, space engineering, etc.
To massively produce microchips very specialized technology machines are used by ASML which is the only company in the world that deals with it. Under extreme ultraviolet light emission (EUV) photonic procedures that are smaller than a nanometer in scale are carried out.
To reflect and orient the light trajectory mirrors, in turn, mirrors specifically designed for such operations are produced by Zeiss. 
Now, when I say mirrors you shouldn't take into mind the mirror you might have in your house (obviously) as it's comparatively imperfect and wouldn't be sufficient for production. By imperfect, I mean that they are rough whereas the Zeiss mirror's surface is hyper-smooth. For comparison, if we would enlarge the Zeiss mirror to the size of Germany the tallest mountain on its surface wouldn't be taller than 1mm high!!! Now, that's what we call "German Engineering" hey?! That maketh it the flattest on earth.

Coming back to the original topic it is concluded that inside a small workshop in Germany a man who was pursuing his passion achieved results that he would never think of! Starting with glasses to microscopes, binoculars, space cameras, med technology, and microchips Zeiss' optics technology continues to make world-scale progress!

If you reached this point I shay say thank you for being with me today.
I'll catch you on the next one. Peace!
