Additionally it is necessary to raise and lower the condenser and you need two centering screws for the condenser. In some microscopes the condenser is already centered, so this is not a big requirement.

Koehler illumination offers a range of advantages over “critical illumination”. Illumination is more uniform, specimen heating is reduced as well as light reflections for photographic work. Some microscopes are equipped with a field diaphragm in the light source. This Koehler illumination, while not absolutely required for simple microscopic work conducted in schools, does offer several advantages:

Hi, The existing lamp stays, but you need a field diaphragm and some lenses mounted above the lamp. The question is, if your microscope allows for this, and if these extras exist for your microscope brand. Some microscopes already have these built in. I would contact your dealer to see if this is possible.

The Koehler field diaphragm is designed to restrict the light beam only on this part of the specimen which is actually observed. Especially at high magnifications only a very small part of the specimen needs to be illuminated.

Vision lighting is the key to creating all-important contrast between the feature of interest and its background when used with a camera.

Oliver, I found this article very educational. I have been considering a Koehler lighting system for some time. Several questions remain that might be helpful in making my decision.

– Does the Koehler lighting system replace my present built in adjustable lighting system on my microscope.? – If so, how does the Koehler system mount or attach to the microscope? – Are any other light adjustments necessary between the Koehler system and the slide, ie; the condenser aperture diaphram, etc. – Does it work well with the Abes dark field, oblique illumination and the Phase Contrast equipment?

Some animals can't see red light so it's good for nigth hunting and is good for map reading because it doesn't disturb night vision. Flashlights with red ...

Opening and closing the field diaphragm, should not affect the brightness of the image. The system merely restricts the light to the place on the specimen which is actually viewed. Except centering and lowering/raising the condenser, you should not need any extra adjustments. Once set up, Köhler illumination does not need any additional adjustments except opening/closing the field diaphragm.
