Abstract: A domed shaped housing (10) and a divider wall (16) forms a two-compartment structure. A forward compartment forms a workstation enclosure having hand-receiving openings (34, 36), a vacuum system (70, 72, 74, 76) and an air delivery tube (78). The rear section (86) of an articulated boom (82) may extend through a window (46) in the rear compartment and at its lower end be connected to a frame (18). The articulated arm (82) includes a forward section (88) extending forwardly from the rear section (86) and supporting a microscope (84) at its lower end. Lights (54, 66, 64) are provided to light up the forward section of the enclosure (10). A tool holder (80) may be mounted on the divider wall (16).
