The tube is attached to a tripod. For tripod mounted also the stage in which center there is a hole underneath it and a mirror.

To find out how increases image using a microscope, it is necessary to multiply the number shown on the eyepiece, the amount identified on the used object. For example, if the eyepiece gives 10x and 12x lens, the overall increase in the 10×12 = 120 times. RULES WITH MICROSCOPE Put microscope stand to their distance of 5-10 cm from the edge of the table. In opening the stage mirror direct light. Place the cooked product on the stage and secure slide fasteners.
Using a screw, gently lower the tube so that the bottom edge of the lens was at a distance of 1-2 mm of the drug. In the eyepiece, see with one eye, without closing and not zazhmurivaya another. Looking through the eyepiece, with screws slowly raise the tube until a clear image of the object. After work, remove the microscope in the case.
