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.

Size 8 - 15
Size: 10-12, Color: Black 5 Pairs
These socks were so well reviewed that I didn't quite believe my boyfriend when he said they wouldn't fit his size 11 feet. So I went and tried them on my own women's size 7 feet and yeah, no. Maybe the arch & heel part could stretch to accommodate his feet (but it would be stretched quite thin) but the toe part is already very snug on my short little toes, there's absolutely no way they'd fit his gangly toes. So I looked at the package to make sure we hadn't been sent the wrong size, only to see "size 8 - 15" on the barcode. So it turns out it doesn't matter what size you pick, this is a one size fits all situation, and that size does not fit the long toes of a tall man's size 11 feet

Quality not as expected
Size: 10-12, Color: Black 5 Pairs
Upon opening the socks looked all right they fit well, but I questioned the durability. Unfortunately, within a few weeks, the stitching started to separate and now their are holes in most of the socks rendering them useless.

made well
Size: 8-10, Color: Black 4 Pairs
These socks fit really well. Comfortable and the price is a breath of fresh air with other brands of toe socks getting crazy expensive. Just went for my evening run and they felt GREAT.

Comfy and Warm
Size: Women 6.5-7.5, Color: Raisin
I'm very happy with these Original Slipper Socks. I normally wear a 6 1/2, so got these in XS/6 1/2-7 1/2. They are a little long on my feet, but they'll do. I'd rather have them be a little long than a little short, and perfectly sized slippers seem almost impossible to find these days. These slipper socks have a nice, comfy wide toe box, and the cushioned sole is soft, warm, and comfy. The suede on the bottom of the sole make these quiet and very comfy to wear around the house. The wool sock uppers are not itchy, but as comfy as a pair of warm socks.

Perfect for cool weather ...
Size: 12.5-13.5 Women/10.5-11.5 Men, Color: Light Grey Ragg Wool
I see a lot of complaints about fit and outdoor use of these ... I mean, these are slipper socks for indoor use! These are not shoes! If you want to walk outside in the snow, put on shoes or boots and then go outside ... I have two pair of these and they are great! I really like the real leather soles and foam insole, instead of the cheap plastic soles that are sold on most house shoes ... They were a little tight on my ankles when new, but they relaxed a bit and fit perfectly now. These are perfect for letting the TV watch you, sauntering, meandering, posing, consuming hot beverages, midnight strolls through the house, napping and all sorts of other indoor inactivity ... It has been a few years, and I must say, my Acorn's are still working strong. It is about 60 degrees inside, and I'm working in the garage on a cold concrete slab. The red stripes look especially special with my Adidas sweat pants.
