Grayfield Optical Inc - High Resolution Optical Microscopes

The Ergonom Lite is our latest addition to the Ergonom range of microscopes specifically designed for biological work where the very highest resolutions are not required.

The Ergonom Lite is ideal for observations of live blood and enables blood analysis to be performed in a quality previously not possible at this price level. For example, whereas conventional light optical microscopes allow cancer cells to be detected at a level of about 30%, the Ergonom Lite microscope allows such detection at a level of just 2% permitting cancer to be detected up to 2 years ahead of conventional methods. When detected at such an early stage, this considerably improves the patients chances of survival with appropriate treatment.

The Ergonom Lite microscope has all the capabilities of the Ergonom 400-6, yet at a maximum true resolution of 300nm, providing full color high contrast images with depth of field from unstained samples including transparent samples (using grayfield contrast method) that would not provide any useful detail on conventional light microscopes.

As with all Ergonom microscopes, the Ergonom Lite does not require any staining or oil immersion, is very easy to use and uses an entirely optical system with an extended working distance of about 1mm or more. Due to the use of lower priced optics, as only 300nm is required, the Ergonom Lite costs less that half of the Ergonom 400-5 microscope, for example, and is affordable for larger clinics and hospitals.

The Ergonom Lite will be available from April 2008 from Grayfield Optical Inc.

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.
