Ergonom versus Light Optical Microscopes
Comparison
The following table compares the capabilities of the Ergonom Microscope with conventional top quality light microscopes:
Reflected Light - Microscopes
Conventional Light Microscope
"State of the Art" Unchanged since the 19th century
Ergonom Microscope
Ergonom-Technology The new standard for the 21st century
Transmitted Light - Microscopes
Conventional Light Microscope
Light reflections cause over exposure (hazy picture). Reduction of over exposure by adjustment of light field aperture which unfortunately also reduces contour sharpness.
Ergonom Microscope
No light reflection and no over exposure. This is the basis for brilliant pictures. Iris aperture used instead of light field aperture. Extremely high contour sharpness.
| Depth of Field: |
Marginal, declines with magnification |
| Resolution (max): |
Practically : 500nm Theoretically: 250nm |
| Natural Colors: | Not possible at high resolutions |
| Sample warmth levels: | Up to 60 °C above room temperature |
| Use of Living Materials: |
Strictly limited due to high warmth levels. Living cells typically survive for only a few minutes. |
| Depth of Field: | Extremely high, infinitely variable, independent of magnification |
| Resolution (max): |
Practically : 100nm Theoretically: 10nm |
| Natural Colors: | Unlimited up to the most extreme resolutions |
| Sample warmth levels: | Max. 5 °C (typ. 2 °C) above room temperature |
| Use of Living Materials: |
Limited only by natural life span of cells. Use of Olbrich-chambers make long-term observations possible. e.g. 2-3 weeks on nerve cells up to several months on the pathogens of the legionnaire´s disease |
Stained Slides
The Ergonom microscopes do not require any form of staining or time consuming preparation. This allows the specimens to be seen in their natural state in natural colors and in high detail.
However, in order to compare the Ergonom with conventional light microscopes, the following images were made with stained slides under a top quality conventional light microscope and the Ergonom 500. Despite the staining, it is obvious that the Ergonom can reveal considerably more details than the conventional light microscope.
