The pre-owned AQ6376 pushes Yokogawa’s Fourier-monochromator platform into the short- to mid-infra-red, resolving spectral detail from 1.5 µm to 3.4 µm with 0.05 nm resolution and 50 dB close-in dynamic range. InGaAs/extended-InGaAs detectors and gold-coated optics deliver –60 dBm sensitivity while tolerating +20 dBm EDFA outputs, so gas-sensing DFB lasers, super-continuum sources and Ho:YAG pump diodes can all be characterised in a single sweep. Built-in acetylene reference lines maintain ±0.05 nm accuracy, and USB/LAN/GPIB control with fast trace export streamlines both R & D and production alignment—providing metrology-grade precision at a fraction of new-instrument cost.

Industry Background & Resource Sourcing

Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
