Light Spectrometer Peak λ is an innovative app that utilizes your iPhone's camera sensor and advanced algorithms to analyze incoming light accurately. By determining the dominant wavelength, this app enables you to explore the intricate details of the light spectrum in your environment. Whether it's measuring the peak wavelength of colored LED light or understanding color mixtures, this app offers insights into color science and perception.

To measure the dominant wavelength, simply point your camera at a white or gray surface, ensuring no other colors interfere. The app provides automatic warnings for unreliable measurements due to uneven surfaces or insufficient light. While the accuracy varies between devices, following the recommended conditions ensures reasonably good estimations for your measurements.
