Brightfield microscopy uses light from the lamp source under the microscope stage to illuminate the specimen. This light is gathered in the condenser, then shaped into a cone where the apex is focused on the plane of the specimen. In order to view a specimen under a brightfield microscope, the light rays that pass through it must be changed enough in order to interfere with each other (or contrast) and therefore, build an image. At times, a specimen will have a refractive index very similar to the surrounding medium between the microscope stage and the objective lens. When this happens, the image can not be seen. In order to visualize these biological materials well, they must have a contrast caused by the proper refractive indices, or be artificially stained. Since staining can kill specimens, there are times when darkfield microscopy is used instead.

In darkfield microscopy the condenser is designed to form a hollow cone of light , as apposed to brightfield microscopy that illuminates the sample with a full cone of light. In darkfield microscopy, the objective lens sits in the dark hollow of this cone and light travels around the objective lens, but does not enter the cone shaped area. The entire field of view appears dark when there is no sample on the microscope stage. However, when a sample is placed on the stage it appears bright against a dark background. It is similar to back-lighting an object that may be the same color as the background it sits against – in order to make it stand out.

What Makes Up Healthy Blood?

What Makes Up Healthy Blood?

What one sees in the mobile situation are the usual red blood cells, white blood cells, plasma—and what is floating in the plasma. Microbial activity, undigested food, fungi, and crystals are all apparent as is the capacity of the red blood cells to circulate and the white blood cells to devour morbid matter.

(Live Blood Examination in the Darkfield according to Prof. Dr. G. Enderlein)
Darkfield Microscopy or Live Blood Analysis is a way of studying live whole blood cells under a specially adapted microscope that projects the dynamic image onto a video screen. This allows you to view your inner terrain. Digestive, eliminative and immune functions can be assessed as well as the presence of bacteria and other micro-organisms.

The darkfield microscopic examination of the freshly taken live blood is one of the most important examinations of the holistic medicine applied at the Centre. It enables us to view the inner terrain (milieu) and to examine the functions of the red blood cells. It also shows the evolutionary stages of the smallest proteins (endobionts) which are found in every human body. We are also able to see any developed structures such as bacteria, virus and fungus. The darkfield examination shows the state of the blood cells, endobionts and the plasma in a functional and structural way, making bacterial processes and fungal pre-stages in the blood clearly visible.

The darkfield examination is most suitable for the evaluation of chronic diseases; for children who are prone to infections; for recurrent bacterial problems; for candida and other fungal problems and also to answer questions concerning chronic problems of toxicity (e.g. amalgam disturbances).

Dark Field microscopy is a microscope illumination technique used to observe unstained samples causing them to appear brightly lit against a dark, almost purely black, background.

When light hits an object, rays are scattered in all directions. The design of the dark field microscope is such that it removes the dispersed light so that only the scattered beams hit the sample.

The introduction of a condenser and/or stop below the stage ensures that these light rays will hit the specimen at different angles, rather than as a direct light source above/below the object.

The result is a “cone of light” where rays are diffracted, reflected and/or refracted off the object, ultimately, allowing you to view a specimen in dark field.

A dark field microscope is ideal for viewing objects that are unstained, transparent and absorb little or no light.

These specimens often have similar refractive indices as their surroundings, making them hard to distinguish with other illumination techniques.

Dark field can be used to study marine organisms such as algae and plankton, diatoms, insects, fibres, hairs, yeast, live bacterium, protozoa as well as cells and tissues and is ideal for live blood analysis enabling the practitioner to see much more than is possible with other lighting methods.

Already have a microscope, but your microscope manufacturer does not make a darkfield stop? If there is a filter holder below your condenser, a darkfield stop we carry may work. Or you can mount a coin or circle of another opaque material in the center of a clear disk and put it in the filter holder.
