Study Notes
Resolution and Microscope Quality
- Resolution refers to the capacity to deliver a clear image in fine detail, which is a measure of lens quality.
- Good resolution is essential to see small images clearly and distinguish one point from another nearby.
Components of the Microscope
- The microscope has various parts, including:
- Ocular (eyepiece of the microscope)
- Revolving nosepiece (holds and rotates objective lenses)
- Objectives (lenses with different magnification power)
- Stage (platform where the slide is placed)
- Iris diaphragm and lever (control the amount of light passing through the condenser)
- Condenser (concentrates light onto the specimen on the stage)
- Light (light source of the microscope)
- ON/OFF switch (switch used to turn light on/off)
- Arm (curved portion connecting the base and head)
- Coarse adjustment knob (moves stage up and down in large increments)
- Fine adjustment knob (moves stage up and down in small increments)
- Mechanical stage knobs (move stage left and right or forward and backward)
- Light intensity lever (adjusts intensity of the light source)
- Base (supports the microscope and houses the light source)
Instructions for Using the Microscope
- Follow instructor's directions to take a microscope to the workstation.
- Refer to Figure 2-1 and Table 2-1 to familiarize yourself with microscope parts and their functions.
This quiz covers the concept of resolution in microscopy, its importance, and the components of a microscope. It also includes instructions on how to familiarize oneself with the parts of a microscope.
