Flashcards in Compound Microscope Deck (26)
Composed of ground and polished lenses for the enlargement of the image and objects under study.
These are attached to the revolving nosepiece.
The shortest objective, usually marked 4x.
A shorter objective, usually with a magnifying power of 4x-10x with a working distance of 16mm.
Low Power Objective (LPO)
Usually marked 40x-60x with a working distance of 4mm.
High Power Objective (HPO)
Gives the highest magnification with a magnifying power of 97x-100x with a working distance of 1.8mm.
Oil Immersion Objective
Found at the top of the microscope which gives the final magnification of the specimen with a magnifying power of 10x.
Ocular or Eyepiece
These are found below the stage for light gathering and regulation
Has two reflecting surfaces: plane and concave
Found below the stage connected to the condenser and is used to regulate the amount of light by means of a lever
Found below the stage and is used to concentrate light to the specimen under study
Consists of precise parts of metals to support and adjust the optical parts
A heavy U-, V-, or Y-shaped foot that makes the microscope stand stable on any flat surface
A short piece of metal supporting the rest of the microscope
A curved metal for holding microscope
Arm or Handle
A joint between the arm and the pillar that allows possible tilting of the upper part of the microscope
A tubular part attached to the body and bears the upper arm
Facilitates the changing of objectives in focus
Revolving or Rotating Nosepiece
A concave disc which protects the objectives from dust
A platform with central aperture for the passage of reflected light from the mirror and where the slides to be observed are placed
Replaces the clips and is used in manipulation of the slide
Controls and facilitates the movement of the slide forward, backward, or from left to right
Regulates the intensity of light given by the microscope
Light Intensity Control Knob
Used to raise or lower the stage to get the right image of the specimen
Larger focusing knob for big adjustments
Coarse Focus Knob
