A miniature microscope objective for a miniature microscope array (MMA) includes
preferably at least three or four lenses including from object to image a first
positive lens, a second positive lens and a third negative lens. The objective
has a numerical aperture (NA) that provides diffraction limited performance, and
is preferably between 0.4 and 0.9 for the four lens design. The magnification of
the objective is below approximately the outer diameter (OD) divided by the field
of view (FOV), and is preferably between approximately 1 and 12, and is further
preferably greater than 4. The ratio of magnification (M) to numerical aperture
(NA) for the objective thereby has a magnitude that is less than substantially 30.
