Personal notes on Kohler Illumination
Kohler IlluminationThis topic was already discussed on the entry of 09/15/2010. See the following link: Kohler Illumanation In the section Set up for Kohler Illumination, a number of steps are listed. I will just add a couple of notes in some of them.
This is the most difficult part of the process. Therefore, it would be best to follow these upcoming instructions to get better results. Bring the condenser down, closer to the sample. If the intensity of light has changed, then play with the condenser’s focusing knobs until you find a bright spot. If the intensity of the light has not changed, close the diaphragm a little more until the view gets dimmer. Then play with the condenser’s focusing knobs until you find a bright spot. Repeat the process until the image of the edge of the diaphragm is best focused.
NOTESThis is a very tedious process. It requires a lot of practice and tolerance. So be patient. |
