What is Phlux Technology?
Phlux Technology, a spin-out from the University of Sheffield, is at the forefront of infrared sensing solutions. Its proprietary Aura family of Noiseless InGaAs® Avalanche Photodiodes (APDs) offers a substantial leap in sensitivity, reportedly up to 12 times greater than conventional APDs. These advanced sensors are engineered to enhance critical applications such as laser range finders, LiDAR systems, and optical fiber test equipment. By enabling extended range, improved resolution, and reduced system dimensions and costs, Phlux's technology is poised to redefine performance standards across multiple high-tech sectors.
