The AQ6375 Long Wavelength Optical Spectrum Analyzer offers excellent performance as an analyzer that covers over 2 μm wavelength. This high quality product was created for researchers and engineers with inadequate test equipment to measure long wavelength ranges. This technology aims to provide high speed measurements with exceptionally high accuracy, resolution and sensitivity. Additionally, troublesome calibration steps and the development of external analysis software is no longer needed. It can be applied on optical fiber communications, laser and optical device test, passive optical devices.
