Company Description
Redlen Technologies is a manufacturer of high resolution Cadmium Zinc Telluride (CZT) semiconductor radiation detectors for a new generation of detection and imaging equipment including Nuclear Cardiology, CT Scanning, Baggage Scanning and Dirty Bomb Detection. The company pioneered a production process for manufacturing advanced CZT semiconductor wafers with its proprietary Traveling Heater Method (THM) technology. Redlen also offers high purity Cadmium Telluride (CdTe) feedstock product to the Thin Film Solar Photovoltaic (PV) market.

Corporate History
Bob Redden, a career metallurgical engineer, recognized the commercial potential of CZT in radiation imaging applications. Bob’s experience in compound semiconductor crystal growth and pure metals refining enabled him to realize that the standard ‘Bridgman process’ used to grow most compound semiconductor crystals would not work well for CZT. Bob believed that the problems of producing CZT could be solved by using a THM solution-growth process. Bob undertook research on THM crystal growth, including assignments for the Canadian Space Agency, conducting zero gravity crystal growth experiments on the MIR space station, which furthered his belief in the THM process.
