    • Anton Van Leeuwenhoek
      Dutch microbiologist, Father of Microbiology, Observed pond water and scrapings from his teeth
    • Robert Hooke
      English Scientist, Coined the term "cell", Invented the simplest microscope through illumination principle
    • Types of Microscope
      • Simple Microscope
      • Compound Microscope
      • Electron Microscope
    • Simple Microscope
      • Simplest type of microscope, Uses concave mirror, Does not contain lamp source
    • Compound Microscope
      • Routine microscope used in clinical use, Uses two sets of lenses to obtain higher magnification, Can or cannot contain own lamp source
    • Electron Microscope
      • Most advanced microscope, Used for quality control and failure analysis, Used mainly with microorganisms
    • Classifying Parts of the Microscope
      • Mechanical Parts
      • Illuminating and Magnification Parts
    • Magnification Objectives
      Lenses that further magnifies the microscopic specimens that are not visible to the naked eye
    • Magnification Objectives
      • SCANNER (Adds 4X)
      • LOW POWER OBJECTIVE (LPO) (Adds 10X)
      • HIGH POWER OBJECTIVE (HPO) (Adds 40X)
      • OIL-IMMERSION OBJECTIVE (OIO) (Adds 100X)
    • Ocular Lens/ Eyepiece
      Lens that is closest to the eyes, Can be 10X or 5X magnification
    • Body Tube
      Part of the microscope that houses the oculars/ eyepiece
    • Revolving Nosepiece
      Turret-like circular mechanism that holds the objectives
    • Stage
      Rectangular platform that exhibits the specimen
    • Stage Clips
      Mechanism that keeps the slides in place
    • Condenser
      Concentrates light that can be found between the stage and the lamp
    • Lamp/ Light Source
      Main illuminating mechanism of the microscope, Can be separated or incorporated in the microscope
    • Diaphragm
      • Iris Diaphragm
      • Disk Diaphragm
    • Iris Diaphragm

      Disk Diaphragm that constricts or dilates
    • Disk Diaphragm
      Rotating disk with holes of different diameters
    • Arm
      Bar that supports the upper assembly of the microscope
    • Base
      Square or Horseshoe-shaped support of the microscope
    • Pivot
      Allows the upper assembly to move in a more comfortable viewing position
    • Knobs
      • Course Adjustment Knob
      • Fine Adjustment Knob
    • Course Adjustment Knob
      Adjusts the distance between the objectives and the stage
    • Fine Adjustment Knob
      Used for sharp and fine focusing of the objects
    • Glass Slides
      Rectangular glass materials where the specimens are mounted
    • Coverslips/ Cover glass
      Small square-shaped materials that used to cover the specimens after mounting
    • Lens Cleaning Solution
      Liquid that is used to clean objectives; makes it free from foreign objects that might interfere in the view
    • Lens Cleaning Paper
      Soft material that is used to wipe excess solution from the lens
    • Stains
      Solutions that are used to visualize microscopic specimens
    • Microscopic Etiquette
      • Carry the microscope in an upright position
      • One hand should be in the base, and one hand in the arm
      • Properly uncoil the lamp cord
      • Always focus first using the scanner position/ Low-power objective (LPO)
      • Always put the prepared slides in the center of the stage
      • Use the coarse adjustment knobs while using lower objectives
      • Use the Fine Adjustment knobs while using higher objectives
      • Always keep both of your eyes open while viewing the specimen
    • Specimen Troubleshooting
      • Always keep the diaphragm open
      • Check if there are any obstructions in the objectives, eyepiece, or the stage itself
      • Make sure that the lamp is on
      • Make sure that the specimen is always placed at the center
      • Always clean the lenses before using it. Make sure to use the correct objective cleaning solution to avoid scratches
      • Make sure that the objectives are properly seated
    • Image Fading Troubleshooting

      • Make sure that the scope does not require a rubber eyecup for proper viewing
      • Make sure that the specimen is not in the medium that obstructs viewing
      • Watch to see if the body tube or stage is shifting or drooping
      • Check the lamp or cord for short circuits
    • Wet Mount Slide
      Slide on which a wet specimen is placed, then covered with a coverslip
    • Staining
      Process of enhancing the distinguishing features of the specimen viewed under the microscope
