Grayfield Optical Inc - High Resolution Optical Microscopes

The Ergonom 4000-3 is the commercial version of the Ergonom 500 microscope that is even easier to use while maintaining the high true optical resolution capabilities.

The new Ergonom 4000-3 microscope is the first to be built entirely to Kurt Olbrich's specifications using custom made components (previous models made use of standard components made by other manufacturers that had to be adapted). This allows the new microscope to be optimised still further and to cut unnessesary costs, while ensuring availability of spare parts as we are no longer dependant on external suppliers. The use of modern CNC machines, in the manufacturing process, allows for the very highest precision using components almost entirely designed and built in Germany. Only the very best components allow for microscopes with such high optical standards.

The Ergonom 4000 series now offer both incident (<100nm) and transmitted light (200nm) capabilities in true color. Ideal for life sciences, the Ergonom 4000-3 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 4000-4 is like the 4000-3 model, yet designed for incident light only. It is NOT possible to add transmitted light capability at a later date. Ideal for imaging electronic wafers, plastics, metallurgy, etc. not requiring transmitted light.

The new Ergonom 4000 series of microscopes are 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.

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.
