Levenhuk MED 10B Binocular Microscope Magnification: 40–1000x. Binocular head, achromatic objective lenses, and an Abbe condenser with an iris diaphragm, and a filter holderLevenhuk MED 10B is a laboratory microscope with a binocular head. It is designed for professional work with microscope slides and can be used for solving various tasks in clinics, scientific centers, research or medical laboratories, educational institutions. The microscope features achromatic optics that delivers a highly detailed image without aberrations and up to 1000x magnification.A binocular head is located at a convenient 30° angle and provides for comfortable extended observations. It is 360° rotatable that allows for moving around a working table or using the microscope for group research. When an entire microscope is being moved, you can accidentally change the focus of the optics or position of a sample. A rotatable head eliminates these situations. The eyepieces and objective lenses are made of the optical glass with an anti-fungal coating. The eyepieces provide 10x magnification and a good view that allows for working with extended samples. The microscope magnification is changed by rotating a revolving nosepiece. It contains four pre-installed objective lenses, a 100x objective lens can be used for observations using oil immersion (a vial of immersion oil is included in the kit). High-magnification objective lenses feature spring-loaded frames.The specimens are placed on a stage with the help of a mechanical scale. The stage is moveable along two axes; fine and coarse sharpness adjustments are available. The light is located under a stage and consists of 5W LED. Its brightness is adjustable. Between the light and the sample, there is an Abbe condenser with an iris diaphragm and filter holder.The light is powered by an AC power supply. The kit includes: Microscope base with a stand 360° rotatable binocular head Achromatic objective lenses: 4?, 10?, 40xs, 100?s (oil) with an anti-fungal coating Wide-field eyepieces: WF10x/18mm with an anti-fungal coating (2 pcs) Abbe condenser N.A. 1.25 with an iris diaphragm and filter holder Filters: blue, green, yellow Vial of immersion oil 5W LED Fuse (2 pcs) Power cord for microscope Dust cover User manual and lifetime warrantyCaution: Please refer to the specifications table for the correct mains voltage and never attempt to plug a 110V device into 220V outlet and vice versa without using a converter. Remember that mains voltage in the U.S. and Canada is 110V and 220–240V in most European countries.
