Levenhuk MED 25B Optical Microscope
Levenhuk MED 25B microscope is a binocular optical device for observations in light and dark fields. It allows you to adjust Koehler lighting, use oil immersion and study microscopic specimens in detail at magnifications from 40 to 1000 times. The microscope will be useful for professional research by microbiologists, chemists, and physicians and will be an excellent choice for laboratory research in various fields of science. All optics are made of glass with anti-fungal coating. The eyepieces are wide-field and provide 10x magnification. They have diopter adjustment, so image sharpness can be easily adjusted to suit your needs. Planachromatic lenses remove chromatism, noticeably correct field curvature, and improve color rendition and contrast. They provide different magnifications, and the 100x objective can be used for oil immersion. The 40x and 100x lenses have spring-loaded frames. For focusing, coarse and fine focusing knobs are used. The binocular attachment is convenient because you can make observations with both eyes. It is tilted 30° and can be rotated 360°. Under the revolving device there is a subject table with a preparation guide. Below that is an Abbe condenser with an iris diaphragm and a filter holder. The kit also includes a dark-field oil condenser. For lighting, powerful halogen backlighting with brightness adjustment is used. It runs on AC power.
