The collimator present in a spectrometer convert the rays from the source to parallel rays .Telescope is used to watch the parallel rays which means for the telescope the object is located at infinity.so that we use telescope.
The purpose of a bicycle is to help people get around.
They have no particular purpose
The purpose of annexure is to acquisition and incorporate an entity.
the purpose is how is is getting bigger
The cost of a laser collimator depends on the type of telescope you have. One could be looking at spending anywhere between $70 and $200 on a laser collimator.
A collimator is used to "bore sight" a scope. It will help ensure that the scope is close to being properly aligned.

Lines will be formed at the opposite side of the observer if the ruled surface of grating faces the collimator due to reflection
collimator. The collimator is a device used in radiology to shape and limit the size of the X-ray beam, allowing radiographers to target specific areas of the body for imaging while minimizing unnecessary radiation exposure to surrounding tissues.

A collimator in a spectrometer is used to ensure that light enters the spectrometer in a parallel beam, which helps in improving the accuracy and precision of the spectral measurements. It helps to reduce divergent light and focus the light onto the entrance slit of the spectrometer, resulting in more accurate spectral data.
Parallel beams of light can be created by using a collimator, such as a lens or a mirror, to straighten and align the light rays in a parallel manner. This involves focusing the light from a source into a beam and then passing it through a collimating device. The collimator helps to eliminate any divergence of the light rays, resulting in parallel beams.
