Study Notes
Microscope Basics
- Overall magnification of a microscope is calculated by multiplying the eyepiece magnification by the objective lens magnification.
- Example: Using an eyepiece magnification of X10 and an objective lens magnification of X40, the overall magnification would be X400.
Resolving Power
- The main factor affecting the resolving power of a microscope is the wavelength of light used.
Types of Microscopes
- Phase contrast microscopes are suitable for observing living cells in their natural state.
Objective Lens
- The function of the objective lens in a microscope is to gather and focus light from the specimen.
Microscope Maintenance
- Regular maintenance and cleaning of a microscope are essential to ensure optimal performance and image quality, and to prevent damage to the instrument.
