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 10: Assembly
4 Assembly The assembly of the microscope stand together with the holder has to be carried out as follows: 1. Microscope stand base a. Stand clamp: Clamp and pillar need to be firmly connected to each other by the screw thread. - Page 11 The next step is to place the microscope head on the holder, by passing the objective through the holder ring until the rest of the head is above the ring. You must use the small silver adjusting screw on the front of the holder ring to fix the head in place.

Page 12: Operation And Functionality
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 OZM-9 series are stereo zoom microscopes, then you adjust the magnification using the two zoom adjustment wheels on the lefthand and righthand side of the microscope head. -
Page 13: 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 14: Adjusting The Stand
5.5 Adjusting the stand Torque of the focus wheels You adjust the torque of the focus wheels by holding one of the two wheels in place and using the other hand to turn the other wheel. Depending on the direction of the turn, the torque will be increased or decreased. On one hand, this function can help to make it easier to adjust the focus and on the other hand it can prevent the microscope head from slipping down unintentionally. -
Page 15: 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 16: 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). -
Page 17: Fitting And Adjusting A Camera
5.8 Fitting and adjusting a camera (OZM 903, OZM 923) 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 18 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 19: 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. -
