Product Introduction
Based on near-infrared single-photon detection technology, high-precision spectral analysis technology, and practical application scenarios, we have launched research and industrial testing products that support the field of extremely weak light spectral detection. Advanced optical detection technology can improve detection sensitivity to the single-photon level, with a detection efficiency of up to 30%, a wavelength resolution of 0.4 nm, and stable and reliable performance. It is mainly applied in spectral detection scenarios such as single-photon sources, entangled sources, fluorescence, and extremely weak light.
