Optical Microscopes with Greater Resolution and More Depth of Field
Welcome to the World of Grayfield Optical Inc.
Unsatisfied with the capabilities of existing light microscopes, he decided to investigate why the resolution, color contrast and depth of field is so limited. His research led to the discovery, in 1976, of a unique new way of building microscopes which no longer suffered many of the constraints of existing optical theory. He found that by using a different approach to optics and a new mathematical approach, he could build microscopes with a large "cylinder of sharpness" (depth of field) and a true resolution of 100nm, while maintaining full contour sharpness and true colors without the need for staining, oil immersion, etc. His Olbrich Lens System (OLS) is the basis of all his future optical systems.
The OLS technology has also been used to develop objectives for extreme image reduction, a quantum leap in the nano lithography of critical dimensions that can be used for compter wafer production.
Kurt Olbrich originally built his microscopes purely for use within his own "Institute for Interdisciplinary Basic Research" providing a service to some of the top companies in industry and research organisations in Germany and the world. Kurt Olbrich has earned an impeccable reputation due to his unsurpassed optical analysis methods which brought him many international research contracts.
In 2002, Kurt built the Ergonom 500 which was the first microscope he designed to be actively marketed.
Due to the high development and manufacturing costs of the Ergonom 500, which made it too expensive for many research labs, he decided to develop a new range of microscopes (Ergonom 4000 series) designed to keep the manufacturing costs lower while making no compromises in quality or important features like ease of use, variable depth of field, variable color contrast and a purely optical resolution of <100nm (reflected light, sample height greater than 50nm) in true time. This flagship microscope is used in various medical labs and for various industrial applications particually in the electronics and plastics industry.
As the Ergonom 4000 microscope is beyond the price range of most researchers, doctors, etc. The Ergonom 3000 series was developed and has now (October 2010) been redesigned to bring it into a price range that is widely affordable.
The updated Ergonom 3000 series has all the important features like depth of field, color contrast etc. with a maximum practical optical resolution of 200nm resolution, yet at a price now comparable with top quality conventional optical lab microscopes with features far surpassing any other optical microscopes available.
Additionally, smaller microscopes with improved depth of field and resolution have been designed:
Grayfield Optical Inc. offers microscopes based on the technology originally developed by Kurt Olbrich.
