Hey there little one! Do you know what a lens is? It's a special piece of glass that can help us see things clearer or bigger. Well, there's a type of lens called a telecentric lens.
Think of it like a superhero of lenses. Its special power is that it doesn't make things look bigger or smaller, but it keeps them the same size no matter how far away they are. Amazing, right?
You know when you take a picture and things look smaller the farther away they are? That's because regular lenses make things look smaller as they get farther away. But a telecentric lens makes everything look the same size, even if it's really far away.
Another cool thing about telecentric lenses is that they can take really accurate measurements of objects. It's like having a ruler built into your camera lens!
So, in a nutshell, a telecentric lens is a superhero lens that doesn't make things look bigger or smaller as they get farther away, and it can even measure the size of things. Cool, huh?
