The interpupillary distance is adjusted by rotating the eyepiece tubes 2 (Fig. 2) in the range of 48–75mm. The distance between the eyepieces matching the observer's interpupillary distance is marked on the adjustment scale 2 (Fig. 2). For convenience, the microscope head is inclined at 45°. Microscope head magnification: 1x.
T RANS M ITTED LI GHT I LLUM INATO R The microscope illuminator allows for setting up Köhler illumination. The illuminator 17 (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 16 (Fig.
The microscope employs broadband filters. The excitation occurs in a selected wavelength range, and the emission filter transmits the entire spectrum with a wavelength longer than the specified wavelength. The G position (Green) means that the fluorescence filter introduced in the optical path emits monochromatic radiation of the green spectrum range of 495–555nm from the overall radiation of the light source (250–900nm).
The camera is powered via a 12V/1A AC power adapter. MONITO R The monitor is designed to use a visualization system of the MAGUS microscope. It is connected to the camera mounted on the microscope to display the real-time images.

1. Unpack the microscope and check the scope of delivery using Section 8 of the User Manual. 2. Take out the stand 1 and place it on a stable work table, remove protective packaging and dust cover. 3. Take out the eyepiece tube assembly 7, remove the dust cover. Insert the assembly into the socket 8. Move the eyepiece tubes upwards or downwards to adjust them to the observer’s height.
10. Place the UV shield 11 and secure it with the screws. 11. Plug both power cords into the power connector on the stand and into the mercury lamphouse power supply. Plug both power cords into an AC outlet. 12. Make sure that all the components are securely and safely mounted. 13.

4. If the filament image is offset from the center of the light spot, manipulate the lateral alignment knob 4 and the vertical alignment knob 5 to center the light source. Fig. 11b. Adjusting the image P LACI NG THE S P EC IM EN Choose the appropriate dish holder from the kit based on its shape and size (Fig.
When you see the specimen image in the field of view, stop rotating the coarse focusing knob. Rotate the fine focusing knob 2 to focus on the specimen and get a crisp image. Fix the coarse focusing lock knob 5 as shown by the arrow in Figure 14. 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.
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.

6 FLUORESCENCE OBSERVATIONS Transmitted light observations are performed as described above in the user manual. The following instructions apply only to the reflected light observations using the fluorescence technique. Select the appropriate fluorescence filters to match the dyes applied. In order to prevent the fluorescence from quenching, the specimens should be placed in the optical path 5–10 minutes after switching on the lamphouse power supply, when the mercury lamp becomes fully operational.

Switch on the mercury lamphouse power supply. Wait 5–10 minutes for the mercury lamp to be in a steady-state operation mode. Adjust the field diaphragm 1 so that the entire field of view is illuminated. If a smaller field of view is required when using the camera, close the aperture to 60-70% of the field.
7 USING OPTIONAL EQUIPMENT U SING THE EYEP I ECE W I TH A SCALE The eyepiece with a scale or reticle can be used to make comparative analysis of the linear dimensions of the individual components of an object. The scale is installed in the plane of the field diaphragm of the 10x eyepiece.

Fig. 31. Replacing the mercury lamp – Re-install the cover on the lamphouse. An "up" arrow indicates the top of the cover. Tighten the attachment screws. – Plug the power cord to the mercury lamphouse. Important! It is strictly forbidden to turn on the lamp until the lamp cover is re-installed. Exposure to the uncovered lamp will cause eye and skin burn.
