Abstract
Cytopathology specimens such as cervical Pap smears, are evaluated using oblique illumination of the specimens (preferably by multiple beams) rather than the axial illumination of standard compound microscopes. The result is improved visualization of the specimens, increased light penetration through the specimens, increased depth of field and enhanced contrast and resolution.
