iris diaphragm lever the iris diaphragm is a shutter within the condenser that can be controlled by a lever to adjust the amount of light passing through the condenser; the lever can be moved to close the diaphragm and improve contrast; if your field of view is too dark, you can open the...
Iris Diaphragm Lever Small lever beneath the condenser, controlling the amount of light passing through the condenser. Coarse Adjustment Knob Located on the arm, moves the stage to bring the object into focus, used with the scanning (4x) objective. Fine Adjustment Knob Located within the coarse ...
NOTE: To position the specimen directly under the objective lens, close the opening on the iris diaphragm until it is almost completely closed by moving the small lever. You should see a small beam of light projected on to the specimen slide. Now use the stage movement knobs to move the...

iris leaves until only a small portion of the diaphragm is visible at the peripheral edges of the viewfield. Similar steps are taken for each objective being used, making sure the microscope is properly configured for Köhler illumination for each objective in turn by adjusting both the field ...
Move your slide away from you using the mechanical stage lever while looking through the oculars. Which way does the “e” move? State the inversion phenomenon in your own words. Part 3: Field of View Thefield of viewis the amount of the specimen you see when you look through the objec...
