CH1: Microscopy

COMPOUND LIGHT

  • Consist of ocular lenses (binocular eye piece) and objective lenses

 

STEREOSCOPE

  • Dissecting scopes

  • Dalawa 'yung silipan

 

ELECTRON

  • Uses beams of electron which make it capable for higher magnification

 

SEM: Scanning

  • Morphological or outside only

  • Surface

TEM: transmission

  • Can see internal structures

 

MICROGRAPH

  • Images produced by microscope

 

 

 

VARIABLES USED IN MICROSCOPY

 

MAGNIFICATION

  • Amount or degree of visual enlargement of an observed object
