An entirely new method in optical microscopy is the Grayfield method, developed by Kurt Olbrich. This method allows you to see detailed structures that are otherwise not even visible with conventional phase contrast microscopes. For example, the Grayfield method allows you to observe the in-vitro decomposition processes of blood. During this transitional phase new viruses and structures arise, which tend to decay and could previously not be made visible due to the lack of suitable microscope techniques.
What are the processes involved that cause cancer? The concepts shown, in this movie by Bernd Muschlien, discuss the processes as they have been seen under the Ergonom microscope.
Originally released in 1991, updated in 2004 and 2006 by Kurt Olbrich and Grayfield Optical Inc.
This unique movie shows the relation between virusses, bacteria and fungi in a scientific approach. You will see images from a microscope in a resolution of 100 Nm and at a true magnification of 25000. Watch vessels and bloodcompositions a a complete new level.
