a trinocular optical microscope with planar objective lenses; setting up the Köhler illumination is available. It will become a true treasure for those who use optical equipment in their professional field, specialists in medical and microbiology laboratories, educational and recreational institutes, research universities. This microscope helps high school and university students in carrying out in-depth biology studying at home. The main feature of this microscope is its optics. The revolving nosepiece includes four planar objective lenses that improve color rendering, reduce spherical aberrations, correct the field curvature (total square of the flat field of view is up to 95% diameter of the observed image). A 100x objective lens allows for observations using oil immersion. The included eyepieces with a wide field of view provide good visibility. The microscope magnification range is from 40x to 1000x. The trinocular head is supplied with a separate optical tube for installing a digital camera (purchased separately). You need a camera for taking pictures of specimens, creating video archives of your observations, and transferring an image to an external screen for demonstrating research to a wide audience. The head is 360° rotatable and its visual part is inclined at 30° for comfortable extended observations. The illumination system of the microscope is also worth mentioning. All observations are carried out in transmitted light (a LED bulb is located in the lower part of the microscope). An Abbe condenser with an iris diaphragm and light filter are used for adjusting Köhler illumination. It is powered by an AC supply. A mechanical stage is movable; its surface is securely protected with graphite coating. The mechanism of coarse and fine focusing adjustment is used for sharpness adjustment; its knobs are located on the body. The kit includes a dust cover for practical storage. Optional accessories in the Levenhuk MED series (purchased separately) allow upgrading your microscope in no time.
