Changing the Magnification
Besides changing the magnification with the zooming body, this microscope system enables the magnification to be changed
by switching the objectives when used with a nosepiece and equipped with two objectives of different magnification ratios.

Image Zooming
The magnification of the zooming body can be changed by turning
the zoom knobs.
The figure shows the knob turning direction and the
corresponding changes in magnification.
Turning the knob backward: Magnification increase
Turning the knob forward: Magnification decrease
Magnification and zoom ratio
SMZ800N: 1x to 8x, 8:1
SMZ1270/SMZ1270i: 0.63x to 8x, 12.7:1
Zooming in/out
Total magnification
The total magnification of the microscope is determined by the formula below:
Total magnification = zoom magnification x object’s magnification x eyepiece’s magnification
When using a vertical tube, replace the eyepiece’s magnification with the C mount adapter lens’ magnification to
calculate the total magnification.
