MAIN

CHARACTERISTICS

The

Series Stereo Microscopes include three types

stereomicroscope

bodies-

VMF,

VMT

and

VMZ.

The Model

VMF

provided

with

one objective pair

built

into

the

binocular stereomicroscope

body,

and the Model

VMT

with

two

parfocal objective pairs

in a

turret

built

in the microscope

body,

while

the

Model

VMZ

features a

continuously

variable zoom system objective control in the
