ActLight

ActLight manufactures CMOS-based photodiodes using its proprietary Dynamic PhotoDetector (DPD) technology that operates at pulsed voltages, eliminating the need for amplifiers with direct digital circuit connection. The technology offers low cost, high sensitivity capable of detecting single photons, digital output, and miniaturization for compact, energy-efficient applications in wearables, smartphones, vital signs monitoring, eye tracking, and optical datacom. Founded in 2011 in Lausanne, Switzerland, the company has raised $4.9M in Series C funding from investors including Swisscom Ventures, Verve Ventures, and EIC Fund. Manufacturer of CMOS-based photodiodes. It offers embedded and stand-alone DPD photodiodes that operate at pulsed voltages. The photodiodes eliminate the need for amplifiers and can be directly connected to digital circuits.
