IdealPhotonics' three-channel photodetector integrates three independent detection units (such as Si and InGaAs) into a multispectral device, enabling simultaneous measurement of different wavelengths (such as RGB or UV-Vis-NIR) through spectral dispersion or filters. Each channel is equipped with an independent TIA or amplifier, supporting parallel signal output, and is suitable for color analysis, multispectral imaging, and process monitoring.Multi-band synchronous detection and channel isolation (>30dB) are achieved, but calibration of the response consistency of each channel is required.
