Light microscopes

Light microscopes

Advantages

  • Cheap to purchase and operate
  • Small and portable
  • Natural colour of the specimen can be observed
  • Living as well as dead material can be viewed
  • Preparation is relatively quick and simple, requiring little expertise
  • Unaffected by magnetic fields

Disadvantages

  • Magnifies objects up to 1500x
  • Preparation may distort specimen
  • The depth of the field is restricted
  • Has a resolving power for biological specimens of around 1nm

Evaluation

Advantages outweigh the disadvantages, however, in some circumstances an electron microscope maybe a better choice
