Levenhuk 320 PLUS Monocular Microscope A monocular laboratory microscope with LED illumination. Magnification: 40–1600xLevenhuk 320 PLUS is a professional laboratory microscope with a monocular head. Due to the achromatic optics and wide-angle eyepieces with a pointer, specialists in research laboratories, diagnostic laboratories, and scientific and research institutions highly appreciate its possibilities. The microscope is suitable for performing observations in various scientific fields and can be applied for pathologo-anatomic, urological, and other research. The microscope features a monocular head that rotates 360°. Its inclination angle is 30°. The revolving nosepiece has four achromatic objectives that deliver a clear and contrast image without aberrations. When a 100x objective is used, observations can be performed using oil immersion (a bottle with immersion oil is included in the kit). The microscope features magnification within the range of 40 to 1600x. The stage is equipped with a mechanical scale. Underneath, there is an Abbe condenser with iris diaphragm. You can install light filters in a microscope. Three filters are included in the kit. LED illumination with brightness adjustment is located in the lower part of a microscope, which is why observations are performed in transmitted light. Illumination is powered by AC supply or rechargeable batteries (included in the kit). A charge provides for about 10 hours of continuous work.
