E200 type biological microscopeDetailed product description：

Characteristics of E200 Biological Microscope:

1. The CFI60 optical system - the world's highest level infinity optical system, was first applied to Nikon microscopes, enabling clear imaging at any magnification.
2. Thanks to Nikon's meticulous ergonomic design, long-term comfortable operation is guaranteed. This is similar to the design of Nikon's other laboratory and research E-series microscopes.
3. Integrated design from rack to base, the worktable lifting mechanism is located inside the base, and the entire length of the guide rail on the machine back is 188.5mm, with better rigidity and shock resistance, and high imaging quality.
4. Nikon's unique invention, the self-healing focusing worktable, eliminates the need for manual refocusing and makes slicing operations safer and easier. After pressing, the workbench can immediately descend for replacing slices or dripping oil on slices. Once the hand is moved away, it returns to its original position. Large working area, can be sliced into two pieces at the same time.
5. When replacing the light bulb, there is no need to lift the microscope. Simply open the light collecting mirror cover and replace the light bulb.
