Nikon Instruments' Eclipse 90i is a fully motorized, ergonomically designed and scalable upright microscope for applications in the fields of medicine, cell biology, drug discovery and biochemistry. A USB interface provides external control, and a digital imaging head improves fluorescence performance. An integrated epifluorescence attachment produces high signal-to-noise contrast ratios. Motorized fine-coarse control operates at 5 mm/s, and an encoder-incorporated Z-axis achieves resolution to 0.05 µm and reproducibility to 0.1 µm. A control switch manages light distribution, nosepiece rotation, fine or coarse focusing, light intensity, filter cube rotation and aperture.

The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
