Collimation is used for telescopes to make sure the telescopes are perfectly aligned. The reflector will not produce the best image if the aligned is not just right.
This term is used in surveying. 'Height of collimation' means height of instrument.Generally this term is used while doing levelling i.e. Measuring elevation of given point.
Collimation refers to the alignment of optical elements, such as lenses or mirrors, to ensure that light rays travel parallel to one another, which is crucial for achieving optimal image quality in telescopes, microscopes, and other optical systems. To detect collimation, one can use methods such as examining star images through a telescope for roundness and clarity, or employing tools like a collimation cap or laser collimator, which project a beam of light to assess the alignment of optical components. Misalignment can lead to blurry images and optical distortions, indicating the need for adjustment.
The height of collimation is the height of the line of sight. It is the vertical distance of the horizontal plane through a telescope.

Light is found by reflecting telescopes and refracting telescopes are used to dected sound
Telescopes are instruments used by astronomers. The first person to do this was Galileo.
The largest telescopes that use visible light are reflector telescopes.
Telescopes are used to see things that are far away from earth. Using telescopes we can see things that are millions of miles away. Most of the telescopes are on Earth but some of them are in space such as the Hubble Space Telescope.
The largest telescopes that use visible light are reflector telescopes.
Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.
