aperature diaphragm control lever- controls the light being illuminated through the specimen. It is located at the bottom of the condenser (also known as the iris diaphragm control lever). arm- The site of attachment for the nosepiece (also known as neck). base- supports the microscope (also known as stand). brightfield illumination- when light passes through the specimen on the microscope slide making it look dark against a bright background. condenser- concentrates the light through the object being viewed. field diaphragm -shutter like covering that can be adjusted to control the size of illumination from the light source before it reaches the condenser aperature. It is located in the base. field of view- the total area visible while looking in the microscope (also known as microscopic field or field). focus control- said in bringing the item of interest into focus. interpupillary control- used to adjust the distance between the oculars. iris diaphragm control lever- controls the light being illuminated through the specimen. It is located at the bottom of the condenser (also known as the aperature diaphragm control lever). light source- makes it possible to see the item of interest. microscopic field- is the total area visible while looking in the microscope (also known as field or field of view). neck- The site of attachment for the nosepiece (also known as arm).nosepiece- the part of the microscope used to secure the objectives. numerical aperature- indicates the ability of the objective lens to collect light. objective- contains the lens used for magnification. ocular- the component of the microscope the clinical laboratory professional looks through to see the magnified item. oil immersion lens- this objective lens has a power of magnification of 100x. optical tube length- the distance from the ocular to the area where the nosepiece connects to the object. optical tube- links the objective lens with the oculars. resolution- the level of detail that can be seen. stage- the part of the microscope that supports the item (for example, a slide) being viewed. stage clip- secures the slide on the stage. stage control- moves the stage. stand- supports the microscope (also known as base). working distance- the distance between the objective lens and the object being viewed when the object is clearly in focus.
