Page 3: Before Use
1 Before use 1.1 General notes You must open the packaging carefully, to make sure that none of the accessories in the packaging fall on the floor and get broken. In general, microscopes should always be handled carefully because they are sensitive precision instruments. -
Page 4: Storage
1.3 Storage You should ensure that the device is not exposed to direct sunlight, temperatures which are too high or too low, vibrations, dust or a high level of humidity. The ideal temperature range is between 0 and 40°C and a relative humidity of 85% should not be exceeded. -
Page 5: Maintenance And Cleaning
• Special cleaner for optical lenses • Special optical cleaning cloths • Bellows • Brush When handled correctly and checked regularly, the microscope should give many years of efficient service. Should repairs still be necessary, please contact your KERN dealer or our Technical Department. OLM-170-BA-e-2310... -

Page 11: Reflected Light Unit
4.1 Reflected light unit The reflected light unit consists of a light source (LED) located in the microscope housing and a polarisation unit. For operation, the USB power cable [2] including the power supply adapter [1] must be connected to the power socket [3] on the rear of the microscope. The aperture diaphragm [1] and a gray filter [2], which must also be inserted in the beam path, are used to modify the light in brightfield mode. - Page 12 For the application of the polarization method, an analyser slide [3] and a polariser slide [1+2] are included in the scope of delivery, which must also be placed in the appropriate slots. See also page 7: Analyser slide / has the name "A" (7) Polariser slide / has the name "P"...

Page 13: Objectives
4.2 Objectives The nosepiece must be in its lowest position so that the objectives can be screwed into it. You can then pass the objectives through the opening of the specimen stage and screw them into the nosepiece, so that when you turn the nosepiece in a clockwise direction, the objective with the next strongest magnification appears. -
Page 14: Eyepieces
4.3 Eyepieces You must always use eyepieces with the same magnification for both eyes. These are simply placed onto the tube connectors, once you have first removed the plastic protective caps. You should always make sure that you do not touch the lenses with your bare fingers and that no dust enters the apertures. -
Page 15: Operation
5 Operation 5.1 Getting started The very first thing to do is to establish the power connection by means of the mains plug. Now the illumination can be switched on via the main switch (dimmer). The light intensity control (dimmer) should first be set to a low level so that the eyes are not immediately exposed to too much light when looking into the eyepieces for the first time. -
Page 16: Pre-) Focussing
5.2 (Pre-) focussing When you are observing an object, you must have the correct distance to the objective to achieve a sharp image. In order to find this distance at the beginning (without other default settings of the microscope) place the objective with the lowest magnification in the beam path, look through the right eyepiece with the right eye and turn it slowly using the coarse adjustment knob. -
Page 17: Adjusting The Interpupillary Distance
5.3 Adjusting the interpupillary distance With binocular viewing, the interpupillary distance must be adjusted accurately for each user, in order to achieve a clear image of the object. While you are looking through the eyepieces, use your hands to hold the righthand and lefthand tube housing firmly. -
Page 18: Adjusting The Magnification
5.5 Adjusting the magnification After pre-focusing has been carried out using the objective with the lowest magnification (see section 5.2) you can then adjust the overall magnification using the nosepiece, as necessary. By turning the nosepiece you can bring any one of the four other objectives into the beam path. -
Page 19: Using Eye Cups
5.6 Using eye cups The eye cups supplied with the microscope can basically be used at all times, as they screen out intrusive light, which is reflected from light sources from the environment onto the eyepiece, and the result is better image quality. But primarily, if eyepieces with a high eye point (particularly suitable for those who wear glasses) are used, then it may also be useful for users who don’t wear glasses, to fit the eye cups to the eyepieces. -
Page 20: Adjusting The Illumination
Polarising unit (Analyser / Polariser) (See page 12) The OLM 170 series provide the possibility to apply the contrasting method of polarised light. For this purpose the analyser and polariser (both of them are included with the scope of delivery) are used. -
Page 21: Changing The Bulb
6 Changing the bulb If a defect occurs in the lighting unit or other electrical components, the Technical Service department of Kern & Sohn GmbH must be contacted for repair. OLM-170-BA-e-2310... -
Page 22: Using Optional Accessories
7 Using optional accessories 7.1 Camera connection Due to an additional beam exit at the rear of the microscope it is possible to connect microscope cameras to the device, in order to digitally record images or sequences of images of an object being observed. After removing the plastic cover on the camera adapter (C-mount 0.5x), which is already located on the camera connection on the back of the microscope, a camera that has a C-mount thread can now be screwed onto the adapter. -
