Our ability to advance is unbelievable when you consider the scope of the human race. Science, in particular, has progressed at an incredibly fast rate; from the discovery of bacteria in 1683 to the remarkable handheld digital microscope cameras we have today, we seem to have no limits.
Microscopes and telescopes are proof of our capabilities — both have allowed us to see unimaginable things through magnification. However, they do it in very different ways. Let’s take a look at the two key differences between microscopes and telescopes.
- Focal Length: Despite the fact that microscopes and telescopes technically perform the same function, they are built differently. Focal length is defined as “the distance between the center of a convex lens or a concave mirror and the focal point of the lens or mirror — the point where parallel rays of light meet, or converge.” Telescopes have objective lenses that produce long focal lengths while microscopes possess the opposite. As a result, the image produced by telescopes is often quite small, while that produced by microscopes is much larger.
- Lens Diameter: If you’ve ever actually seen a telescope in person, you’ll know that they’re quite large devices. This is because they require lenses that are big enough to absorb as much light as possible; since the vast majority of space is extremely dark, only by gathering as much light from the source (a.k.a., a star, astronomical body, or other phenomena) can the object be illuminated. Microscopes come with a built-in artificial light source for the same purpose; because the object being viewed is literally onhand, it can just illuminate it from behind. This means the lens does not have to be nearly as big.
It is precisely because of these differences that we are able to continue to progress and advance scientifically: digital USB microscopes allow the average person the ability to perform their jobs more efficiently, and telescopes have made seeing the unseeable –for example, black holes — possible. Though it’s hard to imagine where we will go next, we will always be moving forward.
