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.
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.

A collimator is used to "bore sight" a scope. It will help ensure that the scope is close to being properly aligned.
The telescope and collimator are adjusted for parallel rays of light in dispersion to ensure that the light entering the system is uniform and consistent. This alignment allows for accurate measurement and analysis of the light's spectral properties without interference from angular variations. By using parallel rays, the dispersion of light through prisms or diffraction gratings can be precisely studied, leading to clearer identification of wavelengths and better resolution of spectral features. This setup is crucial for experiments in spectroscopy and other optical applications.
To conduct a lunar laser ranging experiment at home, you will need a powerful laser pointer, a telescope, a tripod, and a clear night sky. Set up the telescope on the tripod and point it towards the moon. Use the laser pointer to send a beam towards the moon and wait for the reflection to return. Measure the time it takes for the laser beam to travel to the moon and back to calculate the distance. This experiment requires precision and caution when handling the laser.

Lines will be formed at the opposite side of the observer if the ruled surface of grating faces the collimator due to reflection
To collimate a Dobsonian telescope for optimal performance, adjust the primary and secondary mirrors so they are aligned properly. Use a collimation tool to make sure the mirrors are centered and aligned with each other. Fine-tune the collimation by adjusting the screws on the secondary mirror holder and the primary mirror cell until the telescope produces sharp and clear images.
well to my calculations the telephone and the computer are most recent
allow only parallel rays from strem of rays
