             abstract = "Multifocal microscopy is an established technique to combine 
                         several reflected-light microscopy images of an object, each with 
                         a limited depth of focus, into a single image that shows the whole 
                         object in focus. Photometric stereo is an independent technique to 
                         recover the third dimension of an opaque object, given several 
                         images taken from the same viewpoint with different illumination 
                         conditions. We describe here the synergistic combination of both 
                         techniques to obtain accurate three-dimensional images of 
                         microscopic objects. In order to streamline the acquisition of the 
                         necessary images, we developed a low-cost positioner that 
                         automatically varies the microscope-to-object distance and the 
                         light direction, under control of an Arduino microcontroller. The 
                         main structural parts of the support were manufactured by a 3D 
                         printer. The technique and support are demonstrated with a low 
                         cost digital microscope.",
