Levenhuk 850B Biological Microscope (SKU: 24611)

The Levenhuk 850B microscope is a trusted and reliable binocular microscope designed for biological studies. This versatile microscope is suitable for both light and dark field observations, making it an essential tool in various medical laboratories, including dermatology, cytology, and hematology research. Equipped with high-quality planachromatic lenses, the Levenhuk 850B delivers exceptional imaging performance.

The microscope features a 30-degree inclined head that can rotate a full 360 degrees. It incorporates four planachromatic lenses in a turret within the head, along with the Koehler lighting system, aperture diaphragm, and field adjustment. This combination of features ensures optimal conditions for professional observation.

The microscope's stage, measuring 140 x 155 mm, is adjustable in two axes, allowing precise positioning of the specimen. The focus is achieved by manipulating the fine and coarse adjustment knobs, which raise or lower the stage and adjust the distance between the sample and the objective lens. Both adjustment systems operate smoothly, with a range of 25 mm for rough focusing and an impressive 0.002 mm for fine adjustments.

For illumination, the Levenhuk 850B employs a 6 V / 20 W halogen lamp mounted on the microscope base. The brightness of the illumination can be easily adjusted to suit the specific requirements of the observation.

One notable feature of the Levenhuk 850B is its dark field capability. With the Abbe condenser raised to its highest position, the microscope is equipped with a dark field condenser. This dark field microscopy technique is particularly useful for blood tests and other biological samples, as it often provides higher contrast compared to bright field observations. By simply rotating the lighting ring to the right, the microscope can be switched to the dark field mode.
