Magnification | Enlarging object examined |
Resolving Power | Increase lenses magnification |
Simple Microscope | One lens not much magnification like that one would use in the jewerly store. |
ocular lens or eyepiece | More than one lens. Objective lens that formes enlarged images and ocular to enlarge it. |
Opaque Microscope or stereoscope | Used to observe things that are not see through. Has ocular and objective lenses and can only magnify for 10 or 20 times. No cellular details. |
Bright field compound microscope | Can see cellular most used in labs. Can be magnify 40 x 10000 |
Electron Microscope (EM) Ex: Transmission Electron Microscope (TEM). Intercellular structures. Scanning electron Microscope (SEM) 0.0005um | Used to see mitochrondia chloroplast or ribosomes |
Immersion Oil | Used to increase resolving power. Immerse objective lens and the specimen in immersing oil to increase apeture. |
Numerical Aperture (NA) | Helps differentiate details of specimen by imprioving resolution |
