Committed to providing high-precision, small-miniaturized spectral sensing products for innovative applications of customers in consumer electronics, AIOT, and general industries, the chip-level optical SEETRUM domain modulation is realized by using the innovative Ultrapix® technology and micro-nano structure metasuface design with the characteristics of high integration and low cost, and the response band extends from visible light to near infrared. As a material fingerprint, the spectrum is an important information carrier for human understanding of the world. The spectral sensing products is a new optical sensing solution that is in-line detectable, environmentally adaptable, and supports high volume production for the detection and analysis of ambient or artificial light sources, colors, and substances, supporting further refinement management, classification, quality control, and other applications. The spectral sensing series products can provide multi-band optional sensor IC, integrated modular product combination and related algorithms and software, which are suitable for portable, handheld, or miniaturized devices, and realize spectral sensing and analysis applications.
