About the consultant
Consulting services at Optical Diagnostics are performed by the owner: Gerard de Wit (39). Gerard has a background in applied physics:
- Ph.D. (1997) from the Delft University of Technology, the Netherlands (optics group of Prof. J.J.M. Braat).
- M.Sc. (1993) from the University of Twente, the Netherlands (biophysics group of Prof. J. Greve)
Gerard lives with his family in Culemborg,
The Netherlands, but performs consulting services for institutes and
companies all over the world. Before founding Optical Diagnostics,
he gained extensive international work experience at:
- ABB, Baden, Switzerland
- McGill University, Montreal, Canada
- Philips, Eindhoven, Netherlands
- Schepens Eye Research Institute, Boston, USA
- Microvision, Seattle, USA
- Netherlands Ophthalmic Research Institute, Amsterdam
Ophthalmic / Optometric instrumentation R&D
If you need some technical work done in the field of ophthalmology / optometry / vision, Optical Diagnostics most likely will be able to help you. Gerard has experience with the optical aspects of, for example:
- retinal imagers (SLO, fundus cameras)
- spectacle lens designs
- ocular aberrations
- ocular stray light (glare, C-Quant)
- color vision tests
- aniseikonia testing and correction
- perimeters
Contact Gerard to find out how he can be of help to your ophthalmic / optometric project.
Do you need guidance with a basic imaging system? Or do you need a custom designed lens/mirror system? Let Optical Diagnostics help you. Gerard has experience in designing, for example, scanning systems, eye pieces (HMDs), and free-form spectacle lenses. Also he has experience in analyzing the straylight properties of optical systems. At the Delft University of Technology he was trained in using the software tools CodeV and Lighttools. At Microvision he also started to work with Zemax and TracePro. He now own his own copy of Zemax that he uses to do consulting work with.
Contact Gerard to find out how he can be of help to your optics project.
If you need some custom software made, Optical Diagnostics can help you. Gerard has been programming for 25 years and currently uses Delphi to develop applications such as the Aniseikonia Inspector and the Color Vision Recorder. Also if you are in need of a website, Gerard can be of assistence.
