Chapter 3: Tools for Investigating the Microbial World
Microscopes
- Compound- contain at least 2 lenses (obj&ocu)
- resolving power vs magnification (human eye has resolving power of 0.2mm). Shorter the wavelength of beam the greater the resolving power.
- Brightfield microscope-greatest magnif. is about 1000X and resolving power about 0.27um.
