CIRCUIT CARD HOLDER AND MAGNIFIER
The circuit card holder is an adjustable, rotatable holder for virtually any size circuit card. Figure 2-7
shows the circuit card holder [view (A)] and the magnifier unit [view (B)]. The magnifier unit provides
magnification when detail provided by a microscope is not required. The special lens allows the
technician to view a rectangular area of over 14 square inches with low distortion, fine resolution, and
excellent depth of field. The magnifier unit, which includes high intensity lamps, adapts to the vertical
shaft of the circuit card holder.
