ElFys’ patented light
sensing technology

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