    Coarse Adjustment Knob
  • They invented the compound microscope in the late 16th century
    Hans and Zacharias Janssen
  • It attaches the arm to the pillar and used for tilting the microscope
    Inclination Joint
  • It is used to magnify the specimen under study

  • The most common microscope used in science laboratories is the ___________.
    Compound Microscope
  • A type of objective lens with a magnification power of 10x
    Low Power Objective
  • A circular and revolving part connected to the body tube that holds the objectives
    Revolving Nosepiece
  • He is the father of microbiology
    Antonie van Leeuwenhoek
  • What is formula in getting the total magnification power for the specimen.
    TM = Eyepiece lens magnification x objective lens magnification
  • This is the hole at the center of the stage for light to pass through the specimen
    Stage Aperture
  • It moves the body tube upward or downward in lesser increments
    Fine Adjustment Knob
  • A type of objective lens with a magnification power of 40x
    High Power Objective
  • It is used to to secure the specimen slide on the stage
    Stage clips
  • A flat platform where the specimen slide is placed
    Stage
  • Give the two magnifying parts of the compound microscope
    Ocular lens/Eyepiece and Objective lens
  • Give the 4 types of objective lenses
    Scanner/ scanning object, LPO, HPO, OIO
  • A compound microscope that has only one ocular lens or eyepiece
    Monocular Microscope
  • It is a device used to view objects too small to be seen with the naked eye
    Microscope
  • The _______________ hold the different parts together and are used to adjust the magnifying parts and illuminating parts to focus a specimen.
    Mechanical Parts
  • It regulates how much light passes through the specimen and can be controlled using a lever
    Iris Diaphragm
  • It supports the body tube and is used to carry the microscope
    Arm
  • Give at least 1 limitation of the compound microscope
    Limited magnification power, Low resolution for very small structures, It requires thin amd transparent samples/specimen
  • It concentrates light onto the specimen
    Condenser
  • It reflects light and directs it to the object, then reflects the image back to the eyes
    Mirror

    200x
  • A compound microscope that has two ocular lenses is called _________
    Binocular Microscope
  • It provides firm and steady support to the entire microscope
    Base
  • A small cylinder attached to the upper part of the body tube that holds the ocular lens
    Draw Tube/ Eyepiece Tube
  • Give atleast 3 illuminating parts of the microscope

  • Adjust the resolution of the HPO lens using the _____________.
    Fine Adjustment Knob
  • It connects the ocular lens to the revolving nosepiece
    Body Tube
