Specifications
Using the microscope
Illumination (1ST and 3ST Levenhuk Microscopes)
Plug your microscope into a power source or insert batteries, turn it on and choose the required
illumination source. If your microscope is fitted with brightness control, you can also choose
the brightness level of illumination.
Stage inset glass
Frosted glass stage inset may be used for observations of transparent specimens or thin slices of
objects. Place it on the stage and secure it in place with the locking screw. Lower illumination
source should be used during observations with this glass stage inset.
The kit of your new microscope may also include a black and white glass stage inset. Normally,
you would want to use the white side; however, if a specimen is very bright, or colored white, you
should use the black side for additional contrast. Upper illumination source should be used during
observations with this glass stage inset. Before installing the black and white glass make sure to
remove the frosted glass from the stage.
