Grayfield Optical Inc - High Resolution Optical Microscopes

The Ergonom 400-5 is the basic model designed for incident light only. It is NOT possible to add transmitted light capability at a later date. Weighing just 18kg, it is very easy to use, yet provides better than 100nm optical true resolution capability with fully variable depth of field. Ideal for imaging electronic wafers, plastics, metallurgy, etc. not requiring transmitted light.

The Ergonom 400-6 is the standard model offering both incident (100nm) and transmitted light (200nm) capabilities in true color. Ideal for life sciences, the Ergonom 400-6 microscope allows prolonged observation of biological samples in their living state without staining or immersion oil. Ideal for medical and pharmaceutical research, this microscope allows you to view specimens within seconds. Clinics using such microscopes have reported a significant reduction in research time due to the ability to see the reactions of living tissue in-vitro to various medicines which can also significantly reduce the need for animal testing. We recommend the use of our range of heated Olbrich chambers with self sealing openings to allow nutrients and drugs to be injected into it.

The Ergonom 400 series of microscopes are made in Germany to the highest technical standards and available in a wide range of configurations and prices to match your exact needs. Built in a modular way, it is possible to add a wide range of additional features as your requirements and budget allow. As we are a small company, we are able to tailor make the Ergonom microscope to your needs and budget while allowing for future upgrades as required.

For those on a lower budget and usage primarily for blood observations, we recommend our new Ergonom Lite, Blood Microscope.

Ergonom Technology

Depth of Field: All Ergonom microscopes feature variable depth of field where the true colours and contour sharpness remain clearly discernable, even with ever increasing magnifications comparable with that of mid-range scanning electron microscopes. This makes it possible to vary the depth of field independently of magnification, which also allows much more detail to be seen (see image on right), live and in real time!

No Staining, No Oil: The unique optical system provides so much contrast that staining is not required. This allows you to observe the specimens, under a white light source, in their true (living) state, in vivid contrast and true colours even at the highest magnifications. All objectives remain dry as oil immersion is not required.

Grayfield: 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.

Phase Contrast: The phase contrast method is used for all thin-layered structures including fibres and textiles. With conventional methods, focusing is limited by overlapping layers and the structures also have the same fractal index causing the structures to become blurred. The Ergonom technology removes these limitations and provides clear and sharp contours.
