Levenhuk 500B Optical Microscope
Levenhuk 500B is a laboratory microscope with a binocular attachment and achromatic optics. It uses halogen lighting, which is good for examining colored samples. The capabilities of the microscope will be of interest to microbiologists, doctors, ornithologists, veterinarians, biochemists and other specialists. The microscope can also be used for educational purposes in higher education institutions. Observations are carried out in a bright field. The binocular head has a slight tilt, which makes long-term work with the microscope more convenient. If necessary, the nozzle can be rotated in any direction - all 360° are available. Wide-field eyepieces provide a good overview and provide 10x zoom. Four achromatic lenses provide high-contrast and vibrant images, allowing you to view small structures. The general magnification of the microscope ranges from 40 to 1000 times. The 40x and 100x lenses are equipped with spring-loaded front lens frames; the 100x lens can be used for immersion observations. Microspecimens are placed on the object table using a preparation guide. The sharpness of the optics is adjusted using two focusing knobs - coarse and fine. The Abbe condenser with iris diaphragm allows for precise illumination control. The light source is a halogen lamp with a collector, the brightness of which can be adjusted. The backlight unit is located at the bottom; AC power is used for power. The microscope has a robust and reliable design; the body is made of metal.
