A collimator is used to "bore sight" a scope. It will help ensure that the scope is close to being properly aligned.
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.
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.

Lines will be formed at the opposite side of the observer if the ruled surface of grating faces the collimator due to reflection
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.

A collimator in a spectrometer is used to produce parallel rays of light or particles from a divergent source, ensuring that the incoming beam is well-defined and uniform in direction. This improves the resolution and accuracy of the spectroscopic measurements by minimizing the effects of scattering and allowing for more precise wavelength discrimination. By ensuring that the light entering the spectrometer is collimated, it enhances the overall performance of the optical system.

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.
