What is Phlux Technology?
Phlux Technology is a deep-tech enterprise specializing in the development of advanced infrared sensor technology. Originating as a spin-out from the University of Sheffield, the company has gained significant industry attention for its Aura family of Noiseless InGaAs Avalanche Photodiodes (APDs). These components offer a substantial performance advantage, providing up to 12 times the sensitivity of traditional APDs. By enhancing the resolution and range of laser range finders and LiDAR systems, Phlux is effectively reducing the cost and physical footprint of critical sensing infrastructure. The company operates at the intersection of photonics and industrial automation, serving as a key enabler for next-generation optical sensing applications.
