The transmitted light microscope is the classic microscope type for transparent preparations how they are used mainly in the biology and medicine. Characteristically these preparations are on an object carrier and are uncovered with a cover glass. But also rock thin bow in the geology or plastics and threads in the material customer are examined in the transmitted light.
Illumination beam path:
1 = lamp filament
2 = aperture diaphragm
3 = objective pupil
4 = pupil of the observer’s eye
Image beam path:
A = luminous-field diaphragm
B = specimen plane
C = intermediate image in the eyepiece
D = retina of the observer’s eye | |
