Some Facts About Collimation, Telescopes And Alignment Collimators
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.
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.
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 you can enjoy excellent images of the night sky with a Newtonian telescope, collimation can present a problem. These telescopes, when moved, can fall out of alignment and this affects the accuracy of the images that are produced. You can learn to collimate your Newtonian telescope, although for many amateurs this step really won't be necessary and you don't need the same level of accuracy as a professional. When it comes to a professional astronomer, a telescope can be realigned with a device called an alignment collimator. These are used to improve image quality and positioning for professional-level telescopes as well as other optical instruments.
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.
