Refractors and telescopes are different things. Refractors are used to focus on smaller things that are not too big to see through a telescope. As such, they don’t have the power of a telescope. Refractors are used to see larger things like stars, planets, and the like and they can be used to “look through” an object or “see” an object with a much stronger magnified view than a telescope.
This is a good example of how the two types of instruments work differently. In the case of refractors, it is more like taking a picture with a camera lens rather than a telescope. The camera lens focuses your image onto a tiny point, and then a mirror in front of it magnifies it. This is like a magnifying glass, except that you can see the magnified image with a much brighter light source, instead of a tiny, tiny point.
Refractors are used for both photography and microscopy. This is because to focus on a tiny point, you have to use a large enough aperture to focus the light. On the other hand, because you can see the magnified image with a much brighter light source, it is possible to focus on a much smaller one. With refractors you can focus on the magnified image, and then use a mirror to magnify it again, giving you a much brighter view.
Refractors are also used for astronomy, because what you aim at is much brighter than the object you are looking at. For example, the earth is much brighter than the moon. As a result, telescopes are used for very different things. The larger the aperture of the telescope, the better your image of the object can be. But a refractor is only one of a kind.
Refractors are much smaller and less expensive than mirrors. The biggest advantage refractors have over reflectors is that they are less likely to get broken or damaged, and therefore the cost per unit is much lower. For the same cost of a refractor, you can buy 4,000 of them.
Reflectors on the other hand are more fragile and expensive. The most common type of reflector that we see is the parabolic mirror. The parabolic mirror is a very simple piece of glass that is shaped like a cone. This allows it to reflect light that is in the exact direction that the sun is shining. In this way, the parabolic mirror can be used to focus the sun’s light onto a small object.
For our purposes, we will focus on the parabolic mirror reflector. The reflector is made out of two lenses. The first is curved and is focused onto the first mirror. The second lens is curved and focuses the light onto the second mirror. A parabolic mirror is a very cheap, very well-engineered piece of technology.
Refractors are a very popular piece of telescope hardware because of their ease of use, simplicity, and accuracy. A parabolic mirror is a very complicated piece of equipment, and a very expensive one, too. One can easily understand why refractors are so popular, but a lot of very cheap, very well-engineered reflectors aren’t.
Refractor telescopes don’t “reflect” light because they focus it onto an image. The light rays coming from the source reflect into a smaller and smaller space until they hit the first mirror. The second mirror then focuses the light into a smaller and smaller spot. The resulting image is a small circle or a small ellipse (the shape of a parabola). The image does not “reflect” the light, it just allows it to be focused.
While a refractor telescope is perfect for astronomy, it is not a useful tool for everything else. It actually isnt a very good reflection telescope. It just uses a parabolic mirror to focus the light on something. The reason it works so well is because of how it works. Refractor telescopes are often found in the back of shops where people can buy very cheap mirrors.
