Autocollimator – Definition & Meaning

Conclusion

An autocollimator is an optical instrument that is used to measure the angle of an object relative to a reference point. It is commonly used in the field of metrology, which is the science of measurement. The autocollimator is a highly precise instrument that is used to measure very small angles, making it an essential tool in many fields of science and engineering.

Definitions

An autocollimator is a device that uses a collimated light source to measure the angle between two surfaces. It is used to measure the angle of reflection of a mirror or other reflective surface. The autocollimator is also used to measure the angle of incidence of a beam of light that is reflected off a mirror or other reflective surface.

Origin

The word “autocollimator” is derived from the Greek words “auto,” meaning “self,” and “collimator,” meaning “a device for collimating light.” The autocollimator was first developed in the early 20th century and has since become an essential tool in many fields of science and engineering.

Meaning in different dictionaries

The autocollimator is defined in various dictionaries as an optical instrument used to measure small angles or deviations from a reference line or plane. It is also defined as a device used to measure the angle of incidence or reflection of a beam of light.

Associations

The autocollimator is associated with precision measurement, metrology, and optical engineering. It is commonly used in the aerospace, automotive, and semiconductor industries, as well as in scientific research and development.

Synonyms

Some synonyms of autocollimator include angle-measuring instrument, angle-measuring device, and optical angle-measuring instrument.

Antonyms

There are no direct antonyms for autocollimator, as it is a unique and specialized instrument.

The same root words

The root words of autocollimator are “auto” and “collimator.” The word “auto” means “self,” while “collimator” refers to a device for collimating light. These words are also used in other scientific and technical terms, such as “autofocus” and “collimation.”
