Product Name: Nikon NIKON ECLIPSE 90i Fully Automated Research - Grade MicroscopePurpose: Suitable for scientific research in multiple fields such as cell biology, biochemistry, molecular biology, and pathology. It can be used for observing cells and tissue sections, studying protein expression and localization, as well as analyzing disease pathology.Performance: It adopts the CFI60 infinity optical system, paired with Plan Apo VC objectives, which have excellent chromatic aberration correction, presenting clear, high - resolution, and uniformly bright images. In terms of illumination, the transmitted light uses a 12V 100W tungsten - halogen lamp, and the built - in "fly - eye" lens array makes the illumination uniform within the field of view; the epi - fluorescence illumination has a stray - light eliminator, which greatly improves the signal - to - noise ratio, and an excitation light balancer can also be optionally configured to adjust the excitation brightness of different wavelengths. Equipped with a high - precision motorized focusing system, the linear encoder feeds back the Z - axis position of the stage, with a focusing accuracy of 0.05μm. It has a motorized 6 - position objective turret. After objective conversion, the aperture and field diaphragms, filters, etc. are automatically switched to the ideal position, and the moving speed of the motorized stage and the focusing speed are also automatically adjusted according to the objective magnification. It has an advanced digital imaging head that integrates high - signal - to - noise - ratio epi - fluorescence illumination, a binocular tube, dual ports, and optical zoom. When used in combination with DS - series cameras, the microscope status information can be viewed on the display screen, and relevant parameters are automatically recorded during imaging. The observation method can be easily switched by clicking on the computer interface, such as the conversion from differential interference contrast (DIC) to epi - fluorescence.
