- Page 10 MICROSCOPE PARTS STAND The stand has stable ergonomic design. Parts attached to the stand: – revolving nosepiece 3 (Fig. 2) with objectives – stage 13 (Fig. 1) – microscope head 15 (Fig. 2) – lamphouse 12 (Fig. 2). Inside the stand is the focusing mechanism and the power supply for the illuminator. The power supply converts AC voltage to the required voltage to power the halogen bulb.
- Page 11 EY EPI EC ES The microscope kit includes eyepieces 1 (Fig. 1). The eyepieces have long eye relief and are designed to work with or without glasses. Eyepiece diameter: 30mm. Eyepiece magnification: 10x. Field of view: 23mm. Both eyepieces have a diopter adjustment of ± 5 diopters to compensate for the observer's ametropia. R EVOLV I N G NO SE P IECE The revolving nosepiece 3 (Fig.
- Page 12 STAG E The XY mechanical stage 13 (Fig. 1) is fixed on the microscope stand. It is moved using the stage control knob 9 (Fig. 2). The long tiltable stage control ensures user comfort: The hand rests on the table with no strain. When assembling the microscope, the stage can be mounted with the knob on the right or left side of the stage.

- Page 15 Fig. 9. Installing the lamphouse – Install the lamphouse on the back of the stand, securing it with the screws using a screwdriver. – Install the color filter slider, field and aperture diaphragms. Use the removable analyzer and DIC sliders only when using corresponding microscopy techniques.
- Page 16 Using the beam splitting Check the position of the beam splitter levers. Rotate the side/vertical port wheel (on the left side) to select the eyepiece position (See Fig. 11а). Set the beam splitter lever and the Bertrand lens lever, as shown in Fig. 11b. The levers are located on the front of the stand.
- Page 17 Adjusting the diopter Both eyepieces have a diopter adjustment 1 to compensate for the difference in vision between the user’s eyes. Place the 50х objective into the optical path. While looking through the eyepiece with the diopter adjustment set to zero (with the other eye closed), bring the specimen into focus.
- Page 18 Setting up Köhler illumination In the light optical microscope, the image quality depends equally on the optics and on the illumination system, so adjusting the illumination is an important preparatory step. The illumination system affects the image resolution, comfort during long observation, and photo quality when using digital cameras. The Köhler illumination is one of the features of professional microscopes.
- Page 19 7. Reduce the opening of the aperture diaphragm 4. Verify the centering of the aperture diaphragm image; center the image as necessary by adjusting the centering screws 6. Open the aperture diaphragm to match the size of the objective exit pupil. 8.
- Page 20 Open the aperture and field diaphragms all the way. Place the specimen on the stage. Fix the specimen with a spring clip. Do not clamp the specimen too tightly, as this may deform the stage plate or stage itself. Adjust the image by moving the XY control knobs so that the observed section of the specimen is directly above the objective.
- Page 21 CALCUL ATIN G T H E TOTAL M AGN I F I CATI ON The total magnification is the eyepiece power multiplied by the objective power. For example, if the eyepiece is 10х, and the objective is 50х, the total magnification of the microscope is 10х50 = 500х. While using the selected objective, you can place a 1.5x lens into the optical path.
- Page 22 Using these data to determine the actual linear size of the specimen, you just need to count the number of divisions of the eyepiece scale aligned with the area of the specimen being measured, and multiply this number by the scale division value specified in this table.
- Page 23 While doing so, if you set a 50/50 ratio on the microscope head, you will be able to use both the trinocular tube and the right side camera port at the same time. It is important that you choose the proper camera to solve specific tasks with a microscope: using low or high magnification objectives, in the bright field or using other contrast techniques.
