Study Notes

Microscope Overview

An optical instrument designed to view structures not visible to the naked eye.
Composed of multiple lenses providing varying levels of magnification.
Features two sets of lenses: one in the eyepiece (ocular lens) and another in the objectives.

Parts of a Compound Microscope

Eyepiece (Panipat): The lens through which the user looks; typically has a magnification of 10x.
Draw Tube (Hil ahing tubo): A tube that connects the eyepiece to the body tube.
Coarse Adjustment Knob (Dagling pahusay): Quickly changes the elevation of the tube for initial focusing.
Fine Adjustment Knob (Dahang pahusay): Allows for precise adjustments in the tube’s elevation for accurate focusing.
Body Tube (Katawang tubo): Houses the eyepiece at the top and objectives at the bottom, maintaining alignment.
Revolving Nosepiece (Ikuting panaklaw): Holds multiple objectives and allows easy switching between them.
Objectives (Panaklaw): The lenses attached to the nosepiece for different magnification levels.
Stage (Tang halan): The flat platform where slides are placed for examination.
Clip (Pang-ipit): Secures the slide on the stage to prevent movement.
Mirror (Salamin): Reflects light to illuminate the specimen; one side is plain for natural light, the other concave for artificial light.
Base (Takad): The sturdy bottom part that supports the entire microscope structure.
Pillar (Patindig): Vertical support extending from the base, supporting the stage and body tube.
Inclination Joint (Sugpong-panghilig): Allows the microscope to tilt at various angles for better viewing.
Diaphragm (Alikmata): Regulates light passing through to enhance clarity while viewing specimens.

Functions of Key Parts

Stage and Clip: Securely holds the slide in place for examination.
Mirror: Essential for proper lighting of the specimen.
Revolving Nosepiece & Objectives: Facilitate switching between different magnification levels to observe details.
