From its humble beginnings the microscope has undergone numerous revisions since Leeuwenhoek’s day. But its usefulness has certainly not diminished. Numerous types of Microscopes are currently being used. Visit the following for a more detailed description of them. . http://biology.unm.edu/ccouncil/Biology_203/Summaries/Microscopes.htm. 1. When moving your microscope, always carry it with both hands. Grasp the arm with one hand and place the other hand under the base for support.. How to Focus on Specimen. Turn on light source on high. Turn the objective to low (4x). Lower the objective lens so that it is close but not touching the slide. Center the image by moving the stage. Adjust the diaphragm for optimum light. Light Microscope. Simple – uses a single lens. Compound – uses a set of lenses or lens systems. Simple Light Microscope. Compound Microscope. Mechanical Parts. Used to support and adjust the parts. Where do they meet? Where do they “meet”? Train #1 leaves station A and accelerates east at 0.5 m/s/s. At the same instant #1 leaves station A, train #2 leaves station B, which is 1.0 km east of A, and accelerates west at 0.25m/s/s. Relative to station A, where would the two trains pass? Assume they were on parallel tracks. Microscope Review The diagram represents a cell in the field of view of a compound light microscope. In which direction should the slide be moved on the microscope stage to center the cell in the field of view
