Your Loony Uncle in Escondido sent you a small, portable Russian LOMO Microscope (“LOMO” is an Acronym for “Leningradskoye Optiko Mechanichesckoye Obyedinenie” [but Leningrad is now St. Petersburg]). The Instruction Manual for this LOMO Sputiniki Microscope (Russian= little travel companion) is written in Russian and is of limited Use to you. The nasty Flesh-Colored Plastic Carrying Case in which your Sputniki arrived contains a small Allen Wrench. You eventually discover that you can use this Allen Wrench on two Allen Screws below the Stage. These Allen Screws move what you assume to be the Condenser. One of these Allen Screws moves the entire Condenser underneath the Stage back and forth in the “x” Axis; the other of these Allen Screws moves the Condenser back and forth in the “y” Axis. Together, these two Allen Screws correspond to which Control(s) on our MIC 101 Zeiss Microscopes? A. Condenser Focusing Knob B. Mechanical Stage Controls C. Condenser Centering Screws D. Condenser Diaphragm Control MIC 101 Exam 1 Page 2 2. On the Base of your Sputniki is an Optical Unit containing what you assume to be the Microscope Illumination System. On top of this Microscope Illumination System is a thick Rectangular Glass Plate exactly the same Size as a Microscope Slide. Well, OK; it is a Microscope Slide. Black Paint has been applied to the Upper Surface of this Slide such that it has three clear Apertures, one with a Diameter of ~1.0 cm, one with a Diameter of ~0.75 cm, and one with a Diameter of ~0.5 cm. An astonishingly large Metal Lever on the Base of your Sputniki moves this Black-Painted Glass Plate back and forth such that the 1.0 cm, the 0.75 cm or the 0.5 cm Aperture can be positioned immediately above the Microscope Illumination System. This Metal Lever corresponds to which Control(s) on our MIC 101 Zeiss Microscopes? A. Lamp Rheostat Control B. Field Diaphragm Control C. Condenser Centering Screws D. Condenser Diaphragm Control 3. Underneath the Stage and on Top of the Condenser is yet another Glass Plate exactly the same Size as a Microscope Slide. Well, OK, this guy is another Microscope Slide. Soviet Optical Engineering was Solid, if not overly Imaginative. Black Paint has been applied to the Upper Surface of this Slide such that it has three clear Apertures, one with a Diameter of ~1.0 cm, one with a Diameter of ~0.75 cm, and one with a Diameter of ~0.5 cm....
