optical spectrum analyzer

The Yokogawa AQ6373B is a visible-wavelength OSA designed specifically for high-speed, accurate analysis of the short wavelength range. Key Specifications & Features: Wavelength Range: 350 nm to 1200 nm Wavelength Accuracy: ±0.05 nm Wavelength Resolution: 0.02 nm to 10 nm; 0.01 nm in the 400–470 nm range Dynamic Range: ≥ 60 dB (close-in) Level Sensitivity: -80 dBm (in the 500–1000 nm range) Max Safe Input Power: +20 dBm Sweep Speed: Fast measurement capabilities; 0.5 sec for a 100 nm span Sampling Points: 50,001 data points for wide-span sweeps at high resolution Design & Architecture: Features a new monochromator with a steeper passband filter slope for clearly separating closely-spaced spectral signals. Free-space (non-contact) optical input supports single-mode, multimode, and large-core fibers (core diameters from 9 µm to 800 µm). Built-in color analysis function (CIE 1931 XYZ standard). Supports pulsed light measurement with Peak-Hold and external trigger modes. Wavelength calibration using a common low-cost xenon lamp. Key Applications: Short-wavelength lasers, LEDs, passive devices Medical/Bio: Laser therapy, DNA sequencing, microscopy Industrial: Laser micro-machining Consumer electronics: Laser projectors, next-gen optical discs, LED products Telecom: Plastic Optical Fiber (POF) communication R&D for Visible Light Communication (VLC), Li-Fi, and Free Space Optical (FSO) communication
