ABSTRACT:
A optical system for stand alone use or for use with a device for attaching modular electronic components to or removing them from a substrate, including a microscope which is horizontally rotatable through 0.degree., +90.degree.. and -90.degree. positions relative to a component to permit viewing of three sides of the component and thus facilitate alignment of the component terminals with leads on the substrate together with inspection of soldered joints. A unit for vertically rotating the microscope through 90.degree. with respect to the component is also disclosed which includes means for quickly positioning and locking the microscope at a preset vertical orientation such as 45.degree. to further facilitate the alignment and inspection functions. Mirrors are also disclosed which enable viewing of three or four sides of a component in the 0.degree. horizontal position of the microscope whereby the above rotation of the microscope to the +90.degree. and -90.degree. positions may be avoided.
