The 1310nm Band OCT Balanced Photodetector integrates two matched low-noise analog InGaAs PIN detectors specifically optimized for the 1300nm wavelength range. This device combines a low-noise broadband transimpedance amplifier (TIA) with an ultra-low-noise power supply. By utilizing unique detector packaging technology, the SBD series effectively suppresses spectral noise caused by multiple reflections, delivering superior imaging results for 1300nm Swept-Source OCT applications.
