Resumen:
Crystal forms can be indexed using digital pictures taken through a binocular microscope. When taking the picture, the line defined by the intersection between the two faces must coincide with the optical axis of the microscope. The angle can be measured using a software or on the printed image. The information is later processed to calculate the Miller indices of the form. In many cases, the indices can be found by a trial-and-error method, comparing the measured value with calculated angles between possible pairs of faces. This works specially well when the Miller indices are low.
