A bubble in the glass of a camera lens is called a bubble, because that's what it is: if the glassmaker pours molten glass into molds, waits for it to harden then grinds and polishes the lenses to their final shape, there will be bubbles in the glass. As long as they're small and not too numerous, they don't hurt anything.
Nikon invented a way to produce absolutely bubble-free glass that is not used except for the most expensive lenses. To do it, they make the glass in small ceramic crucibles. After the glass is molten, the various metals they put in the glass to affect its light-handling properties are added and the glass has gone through its cook cycle, they set the glass in a special machine that performs a process called annealing. This takes the stresses out of the glass and makes it better. Then they let the glass harden in the crucible. This takes months and is very tightly controlled. When the glass is completely hard, they haul the crucible to a very high height and drop it on a granite slab, causing the crucible and the glass in it to break into a million pieces. Once they have broken glass, they pick out the pieces large enough to make lenses out of and cut and polish it to the proper shapes.

It is called Orb. The wiki definition is as following.
The term orb describes unexpected, typically circular artifacts that occur in flash Photography - sometimes with trails indicating motion - especially common with modern compact and ultra-compact digital cameras.

What is a camera body?
In a camera with a removable lens system, the camera body is all of the camera except the lens mechanism. Many more-sophisticated cameras employ a system of removable/ exchangeable lenses. The "camera body" and the "lens" are often sold separately. What is called simply the "lens," though, is really a lens tube with multiple lenses and multiple adjustment mechanisms. It will have a standard connection point that mates to the lens mount on the camera body.
Can you use camera lens on a video camera?
Basically most video cameras are fixed lens so you cannot put a camera lens in it unless it is specially built.
Can you remove the lens from a fixed lens camera?
Yes I can --> can you?
Can you use alcohol wipes to clean camera lenses?
It would depend on the lens. Higher quality lenses are coated with a substance to help eliminate distortion and light polution. If you look at the lenses glass and you see a multi-coloured reflection on the glass, then it is probably coated. Alcohol should not be used on these lenses. It would be better to use a camera lens specific cleaning cloth to clean them.
What is the piece of curved glass in a camera called?
The curved glass in a camera is called a lens. The lens focuses light onto the camera sensor, allowing the camera to capture an image.
How can I create a DIY macro lens for my camera?
To create a DIY macro lens for your camera, you can use a small magnifying glass or a reversed lens from an old camera. Attach the magnifying glass or reversed lens to your camera using a lens adapter or by holding it in front of the camera lens. Experiment with different distances and angles to achieve the desired macro effect.

Is convex lens used in camera?
no. its lens like glass for you to see far or near
Does electricity pass through camera lens?
Assuming the lens of the camera is made of glass, the answer is no. Glass is a very good insulator and it would an extremely large current (along the order of lightning) to overcome the insulating properties inherent in glass.
How does a digital camera operate?
Sunlight reflects of the camera, focused by the glass lens it captures a photo or picture.
What part can be found on a camera an eye and a pair of glasses what does this part do?
This part is called a Lens, on the camera and the glasses the are made of either optical glass or optical plastic, in the eye the lens in an organic material. Lens allow light to enter the camera, eye or glasses, and focuses that light on a surface such as the camera's film, the eye's retina, and the glasses wearer's eyes.

What is the best camera to buy for long distances quality pictures?

What are the potential risks associated with using a camera lens with a ground glass focus?
Using a camera lens with a ground glass focus can result in reduced image quality, decreased sharpness, and potential loss of detail in photographs. Additionally, the ground glass may be more prone to scratches and damage compared to other types of lens elements.
How does light go through a camera?
It is focussed by a lens (a sort of high-spec magnifying glass).
What kind of energy is received by a digital camera through its lens?
The energy that enters any kind of camera through the lens is called light.
