Page 4: 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 5: 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 6: Maintenance And Cleaning
1.4 Maintenance and cleaning In any event, the device must be kept clean and dusted regularly. If any moisture should be occur, before you wipe down the device you must ensure that the mains power is switched off (if lighting unit is fitted). When glass components become dirty, the best way to clean them is to wipe them gently with a lint-free cloth. -

- Page 15 In order to ensure the incident illumination, the LED ring light needs to be attached to the bottom of the objective housing of the microscope head. The three fastening screws on the holder of the ring light are used for the mounting. Therefor it is important to pay attention to the groove around the objective housing, which is intended to be the socket for the screws.

Page 16: Operation And Functionality
5 Operation and functionality 5.1 Getting started After assembly, if the microscope is ready for use, then for devices with lighting you must first establish a power connection using the cable supplied. Please see section 5.7 for more details on adjusting the lighting. If the device has a camera connection (OZM 983), then for binocular use, you must let the trinocular toggle rod on the back of the microscope head stay slid-in. -
Page 17: Dioptre Adjustment And Focussing
5.4 Dioptre adjustment and focussing A special feature of stereo microscopes is that they are fitted with an optical unit which has a relatively high depth of field. In order to be able get the most benefit from this feature, each user must synchronise the focussing mechanisms for themselves. The steps to do this are described in the following section. -
Page 18: Adjusting The Stand
5.5 Adjusting the stand All contained joints of the microscope stand can be application-orientated aligned and fixated (see upper picture). The pneumatic spring ensures the height adjustment of the upper part of the microscope stand. For varying the spring force, the adjustment screw on the middle joint of the stand must be used. -
Page 19: Using Eye Cups / High Eye Point Eyepieces
5.6 Using eye cups / High Eye Point eyepieces 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: Brightness Adjustment
5.7 Brightness adjustment There is only the usage of incident illumination available when working with KERN stereo microscope sets. Therefor a LED ring light (see picture below) is required, that can be mounted to the bottom of the microscope head (see chapter 4 Assembly). Provided that the power connection is established, the illumination can be switched on by using the main switch, which is located at the housing rear of the illumination unit. -
Page 21: Fitting And Adjusting A Camera
5.8 Fitting and adjusting a camera (OZM 983) You can connect special microscope cameras and reflex cameras to trinocular devices in the OZM-9 series, so that you can digitally record images or sequences of objects being observed. The connection for this is on the top side of the microscope head (see figure above). - Page 22 To fit a microscope camera properly, you must use an adapter with a C-mount thread, which is put in the adapter connection once the cap is removed. In total there are three focusable adapters to choose from (see figure below). The difference between these adapters is that they have different integrated magnification (0.3x, 0.5x, 1.0x).

Page 23: Using Additional Accessories
5.9 Using additional accessories Auxiliary objectives In order to make the magnification series of one of the stereo zoom microscopes described here even more flexible, there is the option of using appropriate auxiliary objectives. As you can see in Chapter 7 “Features”, you can choose from five different achromatic corrected objectives (0.37x, 0.5x, 0.7x, 1.5x, 2.0x), depending on what is required. -
