The Fein Optic RB50 microscope was designed for research work. Available with an ergonomic tilting trinocular head that adjusts from 5°-35° this microscope was made for comfort. 12v, 100w halogen transmitted Koehler illumination with N.A. 0.9 condenser with iris diaphragm and swing-out top lens for 2x-100x observation gives you full control the amount of light cast on each sample. Polarization, phase contrast and fluorescence are all available. Dual observation teaching heads can be added to the microscope for two, three, four or five viewing stations. Digital cameras and HD monitors are available for documentation, teaching and live image streaming.
