Dexter Research Center has been proud to serve the custom detector needs of leading companies and research organizations in our more than 40 years in business.
Dexter’s compact, high-output, low-noise, 100%-tested products have made big contributions to sensing in health, the environment, security, comfort and climate controls, defense, and our understanding of the universe. We also bring cost reductions in systems design.

Note: for confidentiality reasons, we can’t always specifically identify our customers, their proprietary applications and products, and what precisely we do for them.
We’ve teamed with our customers to help develop everything from the first-ever inexpensive radiometry applications to the smallest thermopile detector in the world: the ST60 Micro – just 0.061” diameter x 0.128” tall. The depth, breadth, and enterprise of the science and technology that Dexter has enabled is astounding.
Our sensors have flown successfully on multiple space shuttle missions, including STS-34 (October 1989), STS-41 (October 1990), STS-43 (August 1991), STS-45 (March 1992), STS-56 (April 1993), STS-62 (March 1994), and STS-66 (November 1994). Also, our 1M detectors were in the very successful horizon crossing indicators used by seven Microsat satellites.
Dexter has helped to bring space technology down to earth. A major manufacturer of high-performance model aircraft found that our ST60 detector enabled its models to retain visual accuracy to their full-size counterparts by dropping the gyro and substituting state-of-the-art infrared thermal technology.
Working equally well on fixed-wing and helicopter model craft, the customer’s industry-leading consumer products sense heat and cold variations between the ground and the sky with a two-degree accuracy to the horizon. This provides a flight recovery time of less than one second with safe landing capabilities.
A new approach to infrared thermometry was jointly developed by John M. Baker, University of Minnesota; John M Noman, University of Wisconsin; and Atsushi Kano of Shizuoka University, Japan. Dexter’s S60M provided the unique combination of features necessary to support the field gear: 1) minimal size and weight, 2) lower power consumption, and 3) improved dynamic response.
Conducted by NASA’s Aura Satellite, Dexter’s DR34 thermopile detectors helped the development of a space-qualified 2.5 Terahertz laser local oscillator (LLO) pumped by a CO2 laser. The NASA Aura Satellite began a successful five-year mission to gather data that accurately predicts long-term ozone concentration in the atmosphere.
Due to Dexter’s unique energy-absorbing materials, our infrared thermopile detectors have a spectral response that’s flat from the ultraviolet to the far infrared.
The spectral sensitivity of the detector is selected by your choice of band-pass filters.
We offer a wide range of optical filters, window materials, and diffractive lenses, which are in stock and available for your applications.
The thermally compensated detector models minimize the effect of sudden changes in ambient temperature.
Dexter also offers internally mounted thermistors, optional internal apertures, and several choices of package aperture sizes to meet your design constraints.
