Rod without function
At present, the rod (1) on the right-
hand side of the stand base (2) is wit-
hout function.
It is intended for future accessories and
is currently still under development.
NOTE:
As soon as the mod-
el is equipped with an additional
function, you will find information
about it on our website: https://

Illustration xx A: Switch off the microscope.
Switch off the microscope
Switch the microscope off using the
main power switch ON/OFF (1). To do
this, select position O (OFF).
MAKE SURE
the supplied voltage
matches the instruments

5. OPTICAL DESIGN: PARALLEL LIGHT (ZOOM TYPE)
NSZ818 is a parallel microscope, using plan apochromatic optical system and can ob-
tain perfect high three-dimensional and visual softer image. Large zoom range and
field of view may be applied to imaging and observation of the image from macro to
micro. It has an 18:1 high zoom ratio, providing superior optical system, high resolu-
tion and ergonomic design.

rical aperture (NA) offers you a clarity to study in-depth. The objective`s wide field of
view (FOV) of 31.4 mm enables to see a wider and more comprehensive sample area.
Plan apochromatic 1x objective
The newly developed plan apochromatic 1x objective with a high numerical aperture
of 0.15 is used as the optical system. This ensures a uniform brightness of the field
of view and a clear and reliable image at high magnification in bright field mode as
well as at lowest magnification.
