The History of UDT Instruments

The evolution of UDT Instruments can be traced to 1967 when a small group at United Detector Technology (UDT) began manufacturing the first commercially available transimpedance amplifiers for planar-diffused and Schottky barrier silicon photosensors. From there, the group went on to pioneer leading-edge technology for photometers, radiometers, fiberoptic power meters, and optical position sensing instruments. By the time the 1980s rolled around, this innovative and highly successful group grew into an autonomous entity known as UDT Instruments.

The momentum generated by UDT's precision photometric instruments ultimately spurred the company to develop an inventive handheld CRT colorimeter for the growing television and computer peripherals markets. UDT's SLS 9400 colorimeter promises to strengthen the company's position as a leader in precision electro-optics instrumentation while meeting the stringent demands of a multitude of CRT calibration requirements. Today, UDT is poised and ready to pursue even greater technological excellence with only one goal in mind: to meet or exceed the ever-changing needs of its customers worldwide.

Service

We still service those light-measuring instruments that we built twenty years ago when possible. So we stay involved with our customers, and put a lot into each business relationship. We know of no company that hires more qualified sales engineers --- people who really understand light measurement principles and practices. This ensures that you get the electro-optic instrument that best fits your application and budget.

Quality

The instrument you receive is certain to be reliable and accurate. We guarantee it. Because we maintain a Total Quality Management (TQM) program that affects every indicator module, sensor head, and optical accessory we sell. And when it comes time for re-calibration, upgrades, or repairs, you'll discover that our service and metrology departments reflect this same commitment to quality and personalized service.

Publications

In addition to our comprehensive "Guide To" tutorial series, UDT regularly publishes articles in trade journals and other scientific literature which we've made available as application notes to explain subtle details and applications of our technology.
