Operation and functionality
5.1 Getting started
After assembly, if the microscope is ready for use, then you must first establish a
power connection
using the cable supplied.
Please see section 5.7 for more details on adjusting the lighting.
Do not forget to remove the cap from the bottom of the objective, so that you will then
be able to see a reflection of the object being observed in the eyepiece.
All important functions which relate to the use of the devices in this document are
described in the following sections.
5.2 Adjusting the interpupillary distance
Different users have different interpupillary distances. So each time a different person
uses the microscope, the gap between the two eyepieces must be re-adjusted.
While you are looking through the eyepieces, use one hand to hold the righthand or
lefthand prism housing firmly.
By rotating outwards or inwards, you can either increase or reduce the interpupillary
distance.
As soon as the lefthand and righthand visual fields exactly overlap each other, this is
the correct interpupillary distance.
5.3 Adjusting the magnification
As the KERN OSE-42 series covers stereo microscopes (without zoom), we will
describe how to set the magnification using the integrated and rotating objective.
For the devices in this series, you can select between three different magnification
factors at any time.
Chapter 6 “Optical data” gives information on the possible overall magnification which
the microscope can produce.
It will also include the optional use of different
eyepieces.
