Study Notes
Components of a Light Microscope
- The eyepiece is responsible for magnifying the image formed by the objectives.
- The alternative name for the eyepiece is ocular.
- The eyepiece has a pointer that helps to locate the object being viewed.
- The adjustment for inter-pupillary distance in the eyepiece allows the user to adjust the distance between the lenses to fit their eyes.
Objectives
- The objectives are responsible for collecting and focusing light from the specimen.
- The oil immersion objective is used to increase the resolution of the microscope by using oil to fill the space between the objective and the specimen.
Nose Piece
- The nose piece is a rotating turret that holds the objectives in place.
- The alternative name for the nose piece is objective revolver.
Arm
- The arm is the supporting pillar that connects the microscope to the base.
Magnification
- The formula for total magnification is the product of the magnification power of the eyepiece and the magnification power of the objective.
- The alternative name for total magnification is overall magnification.
- The maximum magnification of a light microscope is typically around 1000-1500x.
Focusing
- The coarse focusing knob is used to bring the specimen into rough focus.
- The fine focusing knob is used to make fine adjustments to the focus.
- The purpose of focusing the microscope is to produce a clear and sharp image of the specimen.
Stage and Condenser
- The stage control knobs are used to move the stage and position the specimen.
- The substage condenser is used to focus the light onto the specimen.
- The condenser control knob is used to adjust the height of the substage condenser.
- The iris diaphragm is used to control the amount of light that enters the microscope.
Base and Illuminator
- The base provides stability and support for the microscope.
- The illuminator is the light source that provides light to the microscope.
Resolution
- Resolution (resolving power) is the ability of the microscope to distinguish between two closely spaced objects.
- The resolution of a light microscope is limited by the wavelength of light used.
