‍About ElFys: ElFys provides light sensors with sensitivity better than anything seen before, literally catching every ray of light. The technology greatly improves any light sensing application ranging from health monitoring to analytical instrumentation and security X-ray imaging. The superior performance of ElFys photodetectors is based on an inventive combination of modern MEMS nanotechnology and atomic layer deposition. The core technologies are patented and in the possession of the company.

‍About ElFys' patented technology:
Most light sensing technologies capture about two thirds of light rays, whereas ElFys’ technology can capture all of them. The Black Silicon Induced Junction Photodiode provides superior sensitivity over a wide spectral range, especially in the ultraviolet, as well as an ultra-wide viewing angle. The increased sensitivity provides improvement potential to any applications where light needs to be measured.
