For most of use, the word collimation might sound very foreign and we probably don't know what it means. If, however, you spend a good deal of time working with telescopes, then this term may be familiar. This is especially true for those professional or amateur astronomers that use optical telescopes. These devices help people view distant objects and in order to do so, a collimator can be a helpful tool.
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.
There are several main categories of optical telescopes and these include the catadioptric telescope, the reflecting telescope and the refracting telescope. With a refracting telescope, images are made by an arrangement of lenses, while a reflecting telescope uses mirrors to form the image that you see. The catadioptric variety of telescope actually uses both mirrors and lenses to form images.
In ancient time, optical devices that were similar to telescopes were created and used by civilizations such as Ancient Greece. As the years progressed, so did telescope design and Galileo is the astronomer who truly created the first quality telescopes for the study of the universe. As the years progressed, more advanced forms of telescopes were created including the Newtonian telescope, which was created by Sir Isaac Newton. This telescope design still is used today and can be a very cost-effective and easy-to-use telescope for the astronomy novice or amateur.
One of the difficulties associated with this particular type of telescope is that collimation can be an issue. Collimation basically refers to the alignment of the line of sight in your telescope. When you transport or move your Newtonian telescope, it can move out of alignment and need to be collimated again before you use it. For most amateurs, this lack of alignment is not a huge deal, but you can learn how to collimate your telescope fairly easily. For professional use on more advanced telescopes and optical instruments, it is wise to use a high quality alignment collimator which will direct the light and make accurate positioning far easier.
Alignment collimators are just one type of alignment instrument out there on the market. Proper alignment and calibration is highly important for all types of equipment and not just an optical instrument such as a telescope. All types of machinery must be aligned perfectly in order to ensure that products are created to exact specifications. Companies often hire technicians to come and calibrate and align machinery as needed throughout the year. As you can see, the world of alignment and collimation extends far beyond the needs of the Newtonian telescope.
