10. Do not touch the lens surfaces with your fingers. Use a brush and special lens-cleaning solution to keep the lenses clean. 11. Bulb installation. This microscope employs LED bulbs as a light source. The bulbs should be replaced by the equipment vendor or in a qualified service center. If you replace the LED yourself, the illumination function may be impaired.

2 MICROSCOPE PARTS STAND The stand has stable ergonomic design. Parts attached to the microscope stand 7 (Fig. 1): – revolving nosepiece 8 (Fig. 1) with objectives – stage 8 (Fig. 2) – condenser 12 (Fig. 2) – lamp house 10 (Fig. 1) –...
A camera (video-eyepiece) or an imaging system with a monitor is installed in the trinocular tube 12 (Fig. 1) of the microscope head using a C-mount 1x adapter. The light path splitting ratio: 50% trinocular tube, 50% eyepieces. EY EPI EC ES The microscope kit includes eyepieces 1 (Fig.
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.
Fig. 3. Assembling the microscope 8. Remove the desired dish holder 8 from the package and place it in the stage attachment for moving the specimen in X/Y directions. If you do not need to move the specimen in X/Y directions, loosen the screws and remove the attachment.
A DJ U ST I N G T HE C ON D EN S ER Rotate the phase-contrast slider 1 to the center position corresponding to the transmitted light. Fig. 5. Adjusting the condenser ADJ U STI N G THE E YE P I ECE T UB ES Adjust the interpupillary distance.
Fig. 8. Moving the specimen The stage attachment features an XY control system. The control knobs are coaxial – they are located on the same axis. The knob 2 controls longitudinal (Y-axis) movement, the knob 3 controls lateral (X-axis) movement. Moving range: 77mm in Y-axis direction and 112mm in X-axis direction.
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.
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.
Do it as follows: – While observing the specimen through the eyepieces, find a distinctive point in the field of view (an easily identifiable target, such as point S in Fig. 13а), move the specimen on the stage so that the point is in the center of the field of view, as shown in Fig.
5 PHASE-CONTRAST TECHNIQUE The condenser allows utilizing the phase-contrast technique. Brightfield observations are performed as described above in the user manual. The following instructions apply only to the phase-contrast operation mode. Adjusting the phase-contrast device: 1. Fully open the aperture diaphragm 5. 2.
6 USING OPTIONAL EQUIPMENT EY EPIECE WIT H A SCA LE 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. The eyepiece 1 DIV.
