Die Beugung (Diffraktion) war seit Huygens und Fresnel bekannt. Erfahrene Mikroskopiker kannten viele praktische Tricks. Um feine Details des Objekts zu erkennen. Mikroskope nach Abbe konnten dennoch die bis dato geltenden Auflösungsgrenzen sprengen. Seine Experimente und theoretischen Überlegungen führten gezielt zur physikalisch möglichen Auflösungsgrenze.
Auch 150 Jahre nach Abbes Berechnungen zur Beugung an Objektiven ist die Optikentwicklung ein keineswegs abgeschlossenes Forschungsgebiet.
Glasbläser aus dem Thüringer Wald wie Heinrich Geißler ermöglichten mit ihrer Vakuumtechnik wissenschaftliche Entdeckungen, etwa Spektralanalyse und Röntgenstrahlen. Mit Zeiss-Technik konnten in der Frühphase der Quantenphysik neue Atomspektren entdeckt werden (Bergmann Serie).
Höchste Präzision, geringe Dimensionen und rationale Fertigung prädestinieren die optischen Elemente aus dem Fraunhofer-Institut für Angewandte Optik und Feinmechanik IOF (Jena), um in Erkundungssatelliten eingesetzt zu werden. Höchste Zuverlässigkeit und Lebensdauer sowie originelle Leichtbauprinzipien sind weitere Kennzeichen für Weltraumanwendungen.
Bei vielen Dingen des täglichen Lebens wie zum Beispiel von Brillen bis hin zu komplexen optischen Komponenten und Systemen sind dünne Schichten bestimmend für deren Leistungsfähigkeit.
Im Oktober 2022 wurde der deutsche Zukunftspreis vergeben für die Entwicklung des Mikroskopsystems ZEISS Lattice Lightsheet 7. Das ist ein Höhepunkt einer Jahrhunderte währenden Entwicklung zur Sichtbarmachung feinster, mit bloßem Auge nicht wahrnehmbarer Strukturen. Es ermöglicht biomedizinischen Forschern erstmals, lebende Zellen über Stunden oder Tage hinweg live und in 3D zu beobachten. Sie untersuchen damit beispielsweise, wie die Zellen auf bestimmte Wirkstoffe reagieren oder was geschieht, wenn Viren oder Bakterien in Zellen eindringen.

Great Value Replacement Kit for Eufy C10
I recently picked up the Eufy C10 robot vacuum and absolutely love it, so I was excited to find this accessory kit. This is a much more economical way to stock up on all the wear-and-tear parts your robot needs. Everything fits perfectly, the quality feels solid, and it includes all the essentials—main brush, side brushes, filters, and disposable dust bags. Having these on hand makes maintenance easy and keeps the vacuum running at peak performance. If you own a Eufy C10, this kit is a no-brainer.
Pros
• Excellent value compared to buying parts individually
• Includes all common replacement items
• Fits the Eufy C10 perfectly
• Good build quality on brushes, filters, and bags
• Easy snap-in replacement with no tools required
Cons
• None so far
Verdict
A smart and affordable way to maintain your Eufy C10. Everything you need in one kit, good quality, and great peace of mind. Highly recommended.

Complete Kit at a reasonable price. Fits my Omni S1 Pro!
Color: Omni S1 Pro Accessories kit(14 Pieces)
I love my Omni S1 Pro robotic vacuum. Being able to get a complete resupply pack for my vacuum is wonderful. The whole kit at the coupon value is very reasonable.
The mop roller and brush fit my Omni S1 Pro robotic vacuum with no issues. The bags slide right into the charger base and are detected like my other bags I use.
Very pleased with the kit will order again

This really sucks!
This vacuum is awesome. It is replacing my old Shark which finally could not connect to the WiFi anymore. This has stronger suction power, even on just the standard power, not even turned to turbo. The little tower on top of it prevents it from going under only a few items in my home. But it is nice that it doesn’t bang into walls to turn around. It comes up to an item, slows down and then turns.
I did have to set up two no go zones, which is very easy to do once I figured it out on the app. Because it got stuck up under my headboard one time so I made that a no go zone. Our bed sits very low to the ground with only about 3 inches so you can’t really get under it.
I like the bag dump system versus the old vacuum I had which you just pushed the button and all the dust went into the trashcan blowing half of it up in your face at the same time. So this is very nice.
I have had this a few weeks now and I did look at a YouTube video on how to navigate the app. It does so much more than my old vacuum did and it really is nice. The noise is not any louder than the other one. This one stays longer to empty on the base because it also has a little cutter that cuts the hair out of the roller. This is great because of dog hair that would continually get trapped on my old vacuum.
I think this vacuum is well worth the money which some of the others were so much more expensive. Battery life seems to be about right for the amount of time that it vacuums and then of course it goes to recharge and comes back out to finish the job. The mapping is awesome and is very detailed, and you can even see where the vacuum is on the map and watch it moving if it is rolling at the time. This comes in very helpful if it is stuck somewhere.
I definitely recommend this vacuum. We named her Berta for the maid on “Two and a Half Men”.

Eufy: Never Again
It is jaw-droppingly astonishing how AWFUL this thing is.
I can deal with all the little problems: I have to pick up cords and small objects. It gets caught on random things and shuts down. It needs some creepy data-harvesting app that does nothing you couldn't do with a TV remote. I can live with all of this. Well, I'd like a robovac that doesn't need an app, because WHY do you need an app? It's pointless. But that's the way this world is, so I guess I have to deal with it.
But what I can't handle is how BASIC FUNCTIONALITY does not work. It CANNOT KEEP A SCHEDULE! I have a very simple schedule: run every day at 10am. This device is completely and totally incapable of handling such a basic and simple task. Just run once a day, every day. I can worry about everything else. HOW DO YOU MESS UP A CLOCK? It forgets its ONE JOB every single week. I have to go back into the stupid app, re-set the schedule, probably re-set the map because it invented some new horrible map from the bizarro world because it randomly decided my house was actually NOT my house and it needed to re-establish what's up and what's down, and it got all of that wrong, so we have to go through the mapping process again. And that's if I'm lucky. Sometimes it decides to forget the wifi password (WHY DOES IT NEED WIFI????????) so I have to reconnect that too!
And THIS IS EVERY WEEK! THIS IS BASIC FUNCTIONALITY! JUST! RUN! THE! PROGRAM! OH! MY! GOD! You had it right the first time! JUST DO THAT!!!!!!!!
Alarm clocks have been doing this for 100 years now. Even before electricity, people could set alarms using candles or sand. How does an ELECTRONIC DEVICE with INTERNET ACCESS fail to know it's 10am and time to run? WHAT ARE YOU EVEN DOING?
Normally I think people who type in all caps are crazy. But I am SO SO MAD I CANNOT TYPE NORMALLY. IT'S A CLOCK. LITERALLY JUST LOOK AT THE CLOCK. IT'S NOT DIFFICULT. LOOK. AT. THE. CLOCK. STOP. FORGETTING. MY. SCHEDULE.
I don't know why I have bought 4 eufy robovacs. The first one was alright. It was one of their "dumb" vacuums that just bumps into walls. It eventually broke and they stopped selling the parts to fix it, so I bought a "new" (identical but more expensive) model which also eventually broke and they REFUSED to sell me the parts to fix it when it broke. So I bought one of these "smart" ones and it did this thing I'm describing here: forgot, EVERY WEEK, that it is just supposed to run once a day. IT'S NOT HARD. JUST RUN THE PROGRAM! So I wrote a 1 star review and they offered me a refund if I shipped it back in the original packaging. I threw that away so obviously that was not an option. So me in all of my abundant intelligence bought another, thinking it would be better. NOPE. THIS ONE DOES THE SAME THING!
That's TWO entirely separate models, which are wholly incapable of ACTUALLY DOING THEIR ONE JOB IN THE WORLD.
I should mention that the "dumb" models also had a nasty habit of running randomly at 3am and waking me up in a panic. I guess that should have been my first tip-off that this "tech" company cannot understand the single most basic technology of all of human history: time-keeping.
So with 4 eufys under my belt I am extremely, EXTREMELY confident in my decision. Eufy: never again.
I will not make this mistake again. I will scream it from the rooftops if I have to. I will tell all my friends. I will write it in the reviews. Never EVER buy eufy. Their vacuums cannot even do their ONE JOB. HOW HARD IS IT????
