Microscope
Identifying each part of the microscope
| Question | Answer |
|---|---|
| Bottom of the microscope. Provides a sturdy flat surface to support and steady the microscope. | Base |
| Located in the base. The light from the lamp passes directly upward through the microscope. | Substage light |
| Located on the base or arm. The dial allows you to adjust the intensity of the light passing through the specimen. | Light control |
| The platform that slide rest on while being viewed. The stage has a hole in it to allow light to pass through the stage and through the specimen. | Stage |
| Holds the slide in position for viewing and has two adjustable knobs that control the precise movement of the slide | Mechanical stage |
| Small nonmagnifying leans located beneath the stage that concentrates the light on the specimen. | Condenser |
| May have a knob that raises and lowers the condenser to vary light delivery. Generally, the best position is close to the inferior surface of the stage | Condenser |
| Is a shutter within the condenser that can be controlled by a lever to adjust the amount of light passing through the condenser. | Iris diaphragm lever |
| The lever can be moved to the close the diaphragm and improve contrast. If your field of view is too dark you can open he diaphragm to let in more light. | Iris diaphragm lever |
| The knob allows you to make large adjustments to the height of the stage to initially focus your specimen. | Coarse adjustment knob |
| The knob is use for precise focusing once the initial course focusing has been completed. | Fine adjustment knob |
| Attaches to the nosepiece to support the objective lens system. It also provides for attachment of the eye pieces which house the ocular lenses. | Head |
| Vertical portion of the microscope that connects the base and the head | Arm |
| Rotating mechanism connected to the head. Generally, it carried three or four objective lenses and permits positioning of these lenses over the hole in the stage. | Nosepiece |
| These lenses are attached to the nosepiece. Usually, a compound microscope has four objective lenses: scanning (4x), low-power (10x), high-power (40x), and oil immersion (100x) lenses. Typical magnifying powers for the objectives are listed in parentheses | Objective lenses |
| Binocular microscopes will have 2 lenses located in the eyepieces at the superior end of the head. | Ocular lens(es) |
| Most ocular lenses have a magnification power of 10x. Some microscopes will have a pointer and/or reticle (micrometer), which can be poistioned by rotating the ocular lens. | Ocular lens(es) |
