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.
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.
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.
To collimate light for optimal performance in optical systems, use a collimator lens to make light rays parallel. This helps reduce aberrations and improve focus, resulting in sharper images and better overall performance.
A spectrometer typically consists of a light source, a collimator to create a parallel beam of light, a diffraction grating or prism to disperse the light into its spectral components, and a detector to capture and measure the intensity of the different wavelengths of light. The spectrometer then produces a spectrum displaying the intensity of light at different wavelengths.
In short, a spectrometer utilises a wide range of wavelengths from the electromagnetic spectrum whereas a spectrophotometer utilises only a small section of the electromagnetic spectrum (usually only near-visible light....we usually use U.V). Apart from that, the two are actually extremely similar.

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

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.

It is an optical device to study about the spectrum produced by the refraction phenomenon through a triangular prism or obtained by the diffraction phenomenon at the grating.
