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 many optical instruments are used for viewing either tiny items or distant objects, some are used specifically for analysis. These devices are used to measure and then record the degree, rate or quantity of a specific object.
Because the human eye can only see certain types of light and certain colors, we have created machines to help us look at or study different types of signals, such as radio waves and electrical signals. Our eyes can view light within what is known as the visible spectrum, but for humans, there is a vast non-visible spectrum that includes everything from radio waves to x-rays to ultraviolet light and infrared light. Instruments such as oscilloscopes help diagnose malfunctions in electronic equipment, such as computers, circuitry or even automobiles.
Other objects that are used to analyze light include the photometer, which is used to measure the intensity of light. While this has obvious applications in the field of photography, it also is needed to help astronomers measure the amount of light in stars and other celestial objects. Even engineers use photometry to help them determine what type of lighting to use in different types of structures, such as office buildings.
Other interesting optical inventions include alignment telescopes, which allow highly precise measurements in two directions that are perpendicular to one's line of sight. These alignment telescopes are highly important whenever someone needs extremely accurate dimensional data.
