The Levenhuk MED 25B microscope is a binocular model featuring two condensers – a brightfield and a darkfield condenser. Both condensers can be used for a wide range of observations using oil immersion. The microscope has been developed for professional use in the fields of medicine, microbiology, biochemistry and other scientific disciplines, and can be used for research and diagnosis as well as for educational purposes. With a magnification of up to 1,000×, the instrument enables the observation of complex, detailed microstructures; Köhler lighting can be utilised.
The head, which can be rotated through 360°, proves very practical if, for example, you wish to show a specimen to a colleague, but moving the entire instrument would alter the optical settings. The vertical section is angled at 30°, thus enabling fatigue-free observation over extended periods. Wide-angle eyepieces with 10x magnification are included in the set. The eyepieces can be adjusted to different visual acuity levels via dioptre compensation. The revolver holds four plan-achromatic objectives – a 100x objective enables observations using the oil immersion method. Two objectives are spring-mounted to prevent collisions. The entire optical system is coated with an antifungal coating.
A microscope stage with a physical scale holds the specimens. The cross-table can be moved along two axes. Focus adjustment is carried out via coarse and fine adjustment knobs with a finely tuned, smooth-running mechanism. Specimens are illuminated from below by a 20 W halogen lamp. The brightness is adjustable. The light passes through an Abbe condenser with an iris diaphragm; filters can also be used. Three filters are supplied as standard. Furthermore, it is possible to fit a dark-field condenser to the microscope. This is also included in the set and enables observations using oil immersion.
The lighting is powered by a power supply.
