Compact, portable hand-held 25X widefield microscope fits snugly in a pocket or hooks onto a belt.
Two 1" x 2" x 3/4" acrylic see-through containers serve as viewing chambers for pond water or larger live specimens. Needs only natural lighting for illumination.
Extremely simple to use, just snap on a viewing box containing specimen or use the swivel clamp to hold a subject, adjust the tab focus and view. Economical for numerous occupations where specimen testing or field observation is necessary.
