Collimation, The Alignment Collimator & Telescope Facts

If you\’ve never heard about collimation, you probably don\’t spend a great deal of time using a telescope. For amateur and professional astronomers, using an optical telescope is essential. While you probably understand that a telescope helps you view faraway objects, you might not know how these optical instruments work or why you might need to use a collimator.

Not all telescopes need a collimator and not all telescopes are optical telescopes. Radio telescopes, x-ray telescopes and other types of telescopes also can be handy for astronomers, but they will not need a collimator in order to work precisely. With an optical version of a telescope, light is directed and focused and this is how an image is magnified. It doesn\’t have to be just to view the night sky; however, telescopes also are handy tools for ship captains.

These optical telescopes come in several different forms, including reflecting telescopes, refracting telescopes and catadioptric telescopes. With a reflecting telescope, a set of mirrors are arranged in order to reflect light and create an image. With refracting telescopes, the images are created using carefully arranged lenses. The third type of optical telescope, the catadioptric variety, actually uses both of these (lenses and mirrors) to create the image.

Optical telescopes, in very crude forms, were developed by the ancient Greeks although Galileo is credited with improving this optical instrument for its use in astronomy. Sir Isaac Newton developed a reflecting telescope which is known as the Newtonian telescope and this is still in use today. Often this is used by the amateur astronomer because of its low cost and ease of use.

While it has cost and ease of use on its side, Newtonian telescopes can have problems regarding collimation. This means that the alignment of the telescope can need to be adjusted from time to time. Often when you move or jostled the telescope, it will come out of alignment, and collimation is the process by which you align the telescope in order to ensure that you have a clear image. While this might not be something that an amateur needs to be concerned about, professionals who use telescopes or perhaps other types of optical instruments will use a device known as an alignment collimator to ensure accurate positioning.

The alignment collimator is one tool that can be handy for optical instruments because it will improve precision and the quality of the images produced. However, there actually are all kinds of interesting alignment instruments that make our daily lives safer and easier. Every piece of machinery must be calibrated carefully to ensure that every single product or item produced is crafted precisely. Collimation and alignment are important for all sorts of industries, as well as for astronomers.
