3.1.1. The dissecting microscope

The type of instrument required for dissection is a prismatic dissecting microscope and suitable lighting source. Instruments of this kind embody prisms which erect the image, so that we can see our tools moving in the correct directions. A compound microscope is not suitable as it inverts the image. Binocular instruments give stereoscopic vision, enabling us to perceive depth in the object as well as to use both eyes. The most useful magnification is about x 20, and higher powers are neither useful nor desirable.
