Optical Spectrum Analyzer

The Advantest Q8341 is an optical spectrum analyzer for visible radiation with a wavelength range of 350 nm to 1000 nm. Because it uses a Fourier spectrum system with a Michelson interferometer, the Q8341 can measure coherence. With its narrow wavelength resolution of 0.01 nm (with option), the Q8341 is very effective for the evaluation of not only CD/DVD laser diodes, but also for blue-violet laser diodes. In addition, the built-in He-Ne laser acts as a wavelength reference to ensure a high wavelength measurement accuracy of ±0.01nm (with option). Finally, with its fast 0.5 s (with option) measurement speed, the Q8341 is ideal for evaluating temperature characteristics of system components.Features：Measures LDs with high speed and high accuracyHigh speed measurement option: 0.5 sSmall, lightweight platformCoherence measurement resolution: 0.001 mmWavelength resolution (at 650 nm): 0.05 nm (standard), 0.01 nm (option)The measured resolution of the peak wavelength is 0.001 nmWavelength measurement accuracy: ±0.05 nm (standard), ±0.01 nm (option)Max. input level: ±10 dBmMax.
