Raman imaging helps study astromaterials by showing their composition without damaging them. Raman bandwidth is a key marker for this, but it can be affected by the equipment used. To compare results accurately, scientists need to adjust for these effects. By using a special lamp in their microscope, researchers were able to calibrate the Raman bandwidth in each image they took. This method helps ensure that Raman bandwidth measurements are consistent across different instruments and labs, making scientific analyses more reliable.
