Abstract
A microscope is shown of generally clamshell-like configuration having top and bottom parts resiliently joined through a connecting structure. Hand deflection of the parts, resiliently resisted, results in relatively reduced motion between lens and specimen for focusing. The microscope may be formed as a unitary molding of resinous plastic or as a blank of foldable sections, and it may have built-in slide retainers. The light admitting aperture may be used to precisely locate a liquid specimen for viewing within the focal range of the microscope.
