- Page 11 The interpupillary distance is adjusted by rotating the eyepiece tubes 2 (Fig. 1) in the range of 48–75mm. The distance between the eyepieces matching the observer's interpupillary distance is marked on the adjustment scale 1 (Fig. 2). For convenience, the microscope head is inclined at 45°. Microscope head magnification: 1x.
- Page 12 LA M P HOUS E The microscope lamp house allows for setting up Köhler illumination. The lamp house 11 (Fig. 1) is fixed on the microscope stand. The light source – 12V/30W halogen bulb – is adjusted to the optical path and collector lens using three screws 14, 15, 16 (Fig. 2). A collector with a field diaphragm, which is adjusted to match the magnification of the objective positioned in the optical path, is fixed in the lamp house.

- Page 17 When using high magnification objectives, raise the objective all the way up by rotating the coarse focusing knob and enable the coarse focusing lock knob. After that, focus on the specimen using the fine focusing knob. Adjust the coarse focusing tension. The tension of the coarse focusing knob is adjustable and is preset by the manufacturer for convenient use.
- Page 18 O BSE RVI N G SP EC IME N S IN TAL L GLAS SWA R E The microscope is equipped with a stage attachment 1 that enables movement of the specimen in longitudinal (Y) and lateral (X) directions. The object is moved by Y-axis 2 and X-axis 3 coaxial knobs, as shown in Fig.
- Page 19 CALCU LATI N G T HE TOTAL M AGN IF I CAT I ON The total magnification is the eyepiece power multiplied by the objective power. For example, if the eyepiece is 10х/22mm, and the objective is 40х/0.60, the total magnification of the microscope is 10х40 = 400х.
- Page 20 – Place the 10х objective into the optical path. Looking through the eyepieces, bring the specimen into sharp focus. – Switch on the camera as described in the camera’s user manual. – Pull the beam splitter lever 3. If the image on the screen is blurry, adjust the focus using the fine focusing knob. When choosing the camera port, keep in mind that you will view upright images in the main (trinocular) port.
- Page 21 You should use a special stage micrometer (calibration slide) to determine the linear dimensions (in millimeters or microns). The calibration slide is a transparent glass (of the same size as the specimen 1 DI V. = 0 . 0 1 MM slide) that has a micrometer scale with a scale division of 0.01mm etched on the surface.
