Yokogawa AQ6375

The AQ6375 is the first bench-top optical spectrum analyzer covering the long wavelengths over 2 μm.
It is designed for researchers and engineers who have been struggling with inadequate test equipment to measure in these long wavelength ranges. The AQ6375 achieves high speed measurements with high accuracy, resolution and sensitivity, even while providing full analysis features. Troublesome calibration steps and the development of external analysis software is no longer required.

OSA Dynamic Range input optics

The AQ6375 uses a free-space optical input structure, i.e. no fiber is mounted inside the instrument. Giving DUAL PURPOSE, as the instrument accepts both Single-Mode and Multi-Mode fibers without being affected by the high insertion loss from MM-SM fibers matching. The AQ6375 can measure optical power from +20dBm down to -70dBm thanks to its high-dynamic and very low noise components and circuits used for photodetection. This enables precise measurements of both high power and low power sources. Measurement sensitivity can be chosen among 7 values according also to the measurement speed required by the specific test to be performed. The AQ6375 uses a double-pass monochromator structure to achieve high wavelength resolution (0.05 nm) and wide close-in dynamic range (55 dB). Thus, closely allocated signals and noise can be separately measured.
