The 1060 nm OCT Balanced Photodetector integrates two matched low-noise PIN photodiodes specifically optimized for the 1060 nm wavelength band, a low-noise broadband transimpedance amplifier (TIA), and an ultra-low-noise power supply. Utilizing a proprietary photodiode packaging technology, the detector effectively suppresses spectral noise caused by multiple internal reflections, enabling superior OCT imaging performance. It is specifically designed for swept-source OCT (SS-OCT) applications at 1060 nm.
