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.

What happens if the ruled surface of the grating faces the collimator?
Lines will be formed at the opposite side of the observer if the ruled surface of grating faces the collimator due to reflection
Schuster''s technique for focusing the prism spectrometer?
yes this is an impotent method for focusing the spectrometer in-order to obtain the appropriate readings.
Investigatory project about spectrometer?
An investigatory project is a planned experiment for the purposes of research. One investigatory project using a spectrometer would be to use the instrument in order to determine the glucose levels of different types of foods.
Why is a mass spectrometer incapable of distinguishing between ions?
They have the same mass/charge ratio.
Why does the spectrometer have two sets of vernier scales 180 degrees apart?
It is to minimize the error percentage of parallax. Also we can easily identify if the spectrometer has been moved beyond 270 degrees If we take readings on two scales and then average of it, the value would be more accurate
