Advanced solution for thermal control in precision metrology environments

Temperature measurement electronics capable of achieving local thermal stability with µK/√Hz fluctuations in the millihertz range. Ideal for reference metrology, atomic clocks, quantum sensors, and ultra-precision applications.

Market need: The advanced metrology and ultra-precision quantum technology sectors face critical challenges such as thermal instability, which introduces noise and drift that compromise the accuracy of frequency references, ultra-stable resonators, cryogenic detectors, and interferometers. In most current applications, achievable stability is limited in the low-frequency regime (long acquisition times) due to the intrinsic instability of the electronics.
The impact is broad, spanning from gravitational-wave detection and precision astrophysics to commercial metrology applications.

Proposed solution: The proposed solution is a temperature measurement electronics system capable of achieving local thermal stability with fluctuations on the order of µK/√Hz in the millihertz range. It minimizes ambient temperature noise and drift in optical and quantum components, ensuring greater measurement stability. The system can be integrated into vacuum environments without compromising design and enables precise monitoring of thermal expansion in reference materials such as ULE (Ultra-Low Expansion glass), CFRP (Carbon Fiber Reinforced Polymer), among other materials.
