ABSTRACT:
Examining apparatus includes a base portion, a telescoping portion, an illuminating portion, a power supplying portion and a specimen displaying portion. The base portion includes a bottom section and a first sidewall section extending upwardly therefrom. The telescoping portion includes a top section and a second sidewall section extending downwardly therefrom with the top section including a magnifying lens. The second sidewall section is of a size and configuration to provide adjustable overlapping engagement with the first sidewall section. The illuminating portion includes a first support member disposed within the base portion substantially parallel to the bottom section and spaced therefrom. The first support member includes a plurality of spaced first openings with a light emitting diode lamp disposed withing each first opening. The power supplying portion includes circuitry connecting the light emitting diode lamps electrically with a power source and mechanism for actuating the lamps. The circuitry is selectively engageable with the illuminating portion. The specimen displaying portion includes a second support member disposed within the base portion and resting on the illuminating portion. The second support member has major surfaces of the same general configuration as those of the first support member and a plurality of spaced second conical openings with one being aligned over each of the light emitting diode lamps.
