Because the human eye is limited in its visual capacity, man has invented many instruments to help us see objects that are either extremely small, are far away or to help us analyze the properties of various objects. These optical types of instruments are essential tools for many occupations, from medicine to computer science.
One of the main words associated with optical tools is the word scope, which developed from both Greek and Latin words that meant to view, watch or look at an object. There are multiple types of scopes, include several types of telescopes and microscopes. Beyond these optical instruments, we also use scopes to peek inside of objects, whether it is the inner workings of a safe lock or the inside of our body for medical purposes. This could be an endoscope, which is a flexible instrument that can offer doctors a fairly safe way to look for gastrointestinal issues or even cauterize blood vessels or locate and remove polyps.
While the aforementioned instruments are used to help us view the intricate details of objects that are very far away or extraordinarily small, there are also other types of optical devices that allow us to measure the quantity, degree and rate of a specific object or objects. These tools are used primarily for some type of analysis.
The visible spectrum for humans is actually quite small. There is so much that we simply cannot see such as gamma rays and radio waves. However, there are machines we have created to view or measure these parts of the light spectrum that are not visible to humans. One example is an oscilloscope, which is used to help us observe electrical signals. This can be extremely helpful when we need to diagnose problems in everything from circuitry to vehicles.
Photometry, which is the study and measurement of the intensity of light and also the illumination produced by light, utilizes a tool which is aptly named a photometer. Obviously, professional and hobby photographers need to use photometers, but they are used in other professions, as well. For example, an engineer uses a photometer to decide the proper lighting options in houses and buildings. Astronomers will use a photometer to measure the light in distant stars and other celestial matter.
Other optical devices help people make highly precise measurements. The ability to make these measurements has many practical applications. For example, alignment telescopes can be uses to take measurements in two directions perpendicular to the line of sight.
