Edmund Optics (EO) has been a leading global optical solutions provider that has served a variety of markets including Life Sciences, Biomedical, Industrial Inspection, Semiconductor, R&D, and Defense since 1942.
EO designs and manufactures a wide array of multi-element optical lenses, lens coatings, imaging systems, and optomechanical equipment. Led by a staff of skilled optical engineers and scientists, EO is application focused and pursues new ways to implement optical technology, enabling advancements in industrial metrology, semiconductor manufacturing, life sciences, and more. The company employs 1,250+ employees across 18 global locations and continues to expand. EO is a worldwide presence in industrial optics extending well beyond our original manufacturing plant and corporate headquarters in Barrington, New Jersey, USA.
Or that what's happening inside is actually fusion because of the insane temps of tens of thousands of degrees just on the surface alone, hence the name - a star in a jar.
Hi, this may sound stupid, but I'd like someone to make a video to further refute the crazy flat earther conspiracies. Some of them claim that moon light actually creates cold, which doesn't make any sense. I know it won't be as spectacular as melting rocks, but do you think you could try to see how much heat the death ray can generate from the moon light? Maybe enough to melt cheese or set paper on fire? Any kind of heat would be enough to categorically prove that moonlight is 'hot', because it is a small reflected portion of the sun.
This explanation is sometimes call the Marching Soldier analogy, often formulated by imagining rows of soldiers marching from tarmac into mud. This type of explanation is wrong and does not explain why light bends.
sooo many times i forget there are more types of light sources than the ones our eyes can pick up, and then for the nth time I'm surprised to see things normally not visible 😅 in science-y videos like yours 🔬
Yes! That's how it works for light coming in from far away, which those lasers simulate. But things can behave weird in other situations. Like if you get closer to a convex lens than its focal length, it spreads out light and magnifies what you're looking at (that's how magnifying glasses work)
Das geößte problem zur zeit mit solar energie ist ja das man iregendwo 100 pannels hinstellen muss weil solar strahlen überall verstreut sind aber so werden sie auf eine fläsche konzentriert
Light passing through the center of any lens proceed unaffected or without deviation. The little deflections you are observing are because you are not placing them at center with accuracy and your source lights are also not 100% parallel.
Things will be blurry if they're more than 500mm away, so this lens won't be very good at industrial espionage 😀 they're used for inspection, like accurately measuring the size of parts on a moving conveyor belt in an automated factory
Objects will only be in focus around 500mm away, while they'll get blurry if they're further away. So you couldn't point this at the Moon and see a tiny patch of it in focus with a telecentric lens

My dreams are ruined. But what if we would create a camera out of a directional, single pixel cameras. Just make a 1920:1080 grid of cameras where each camera captures 1 pixel from straight ahead. Shouldn't something like that have bigger focus range?

How is the path of the laser light visible? It might be possible if there is smoke or dust to scatter off the light but there doesn't seem to be. And why does the beam starts after some distance to the laser ray box??
This light source generates laser lines instead of beams. They're triangles of light expanding away from the box, and we see them because they hit the table below. And you don't see them right away because the light is still expanding from the source and hasn't hit the table yet!
These lenses only have a fixed range close to them where things will be in focus, and anything further away will be too blurry to see anything. So you couldn't see a tiny patch of the Moon in focus with a telecentric lens

These reflections are called Fresnel reflections. This effect has to do with the light's impedance not being perfectly the same in each of the two materials. Impedance describes the opposition to the flow of the electric wave of light. There are some really complicated optical metamaterials with near-perfect impedance matching that eliminate Fresnel reflections, but the rest of the time this happens to light going between any two different materials
Exactly, it only keeps objects in focus for a short distance close to the lens. So you couldn't see a tiny patch of the Moon in focus with one of these
