An alternative configuration features an
EMZ zoom stereo with
trinotube for mounting cameras and a stage
with pseudo-darkfield illumination, which
may bring out features of a specimen not
normally seen under brightfield light.
The zoom stereos
offer a wider range of magnification than
turret or fixed models. Much like the zoom
lens on a camera, zoom objectives increase
and decrease magnification progressively,
causing the specimen to grow or shrink
smoothly in the eyes of the viewer.
