About Us

At Cambridge Research Systems Ltd, we believe that what the company stands for is just as important as what we sell. We are proud to have built a tradition of operating with uncompromising honesty and integrity.

Cambridge Research Systems was formed in 1986 as a partnership between Tom Robson, an electronic engineer, and his father, John Robson, a distinguished Vision Scientist at Cambridge University.

Their idea was to improve the way vision science experiments were performed, by using emerging personal computer technology to display dynamic images on cathode ray tube displays.

From these roots, Cambridge Research Systems has grown into the leading supplier of tools for vision science and we now offer a wide range of visual stimulus generators, eye trackers, stereo, 3D, contrast and colour tests and other specialist scientific products through our website at

In 2000, Cambridge Research Systems was approached by Professor Graham Harding, an expert in photosensitive epilepsy who had been acting as a consultant to the television industry for many years. As Head of Vision Sciences at Aston University, Professor Harding was a long-standing customer of Cambridge Research Systems, and knew that our expertise in creating tools for vision science would be invaluable in creating an automated system to check broadcast images for stimuli likely to provoke photosensitive epilepsy.

Through this collaboration, the Harding Flash and Pattern Analyser was developed.
