Stereo microscopy

optica-binocular_enOur laboratory has a stereomicroscope (Leica MZ-12) with three interchangeable lenses (0,7x, 1.6x and 2x) and 25x eyepieces. This combination allows maximum magnification of 500x.

The stereomicroscope is coupled to a CCD detector (Sony SSC-C370P) that sends the signal of MZ-12 to a monitor.

Finally, a videoprint (Sony EPM-1200A) is connected to the monitor and allows us to print on paper the image displayed in the monitor. The analytical photomicrography is useful to study cracks, the signature integration, brushstrokes, to obtain microsamples and even to see if a pigment has a synthetic or a mineral nature (synthetic ultramarine in front of lapis lazuli, for example).
