Advantest Q8341 光谱分析仪|OSA|日本爱德万
2003年7月16日,日本东京,爱德万测试宣布Q8341光谱分析仪开始销售。Q8341具有测试短波长激光二极管的世界上最快的速度,专门用于对蓝光激光二极管的研究。
最近,光盘驱动器DVD-player、CD-player的需求快速增长,据预计年内在日本DVD的发行量可能超过VTR。在这快速的增长之下,日益下降的价格需要我们提高激光二极管的产量来降低价格。
Q8341是一台针对短波长激光二极管的光谱分析仪,波长测量范围从350到1000nm。它采用了傅立叶变换干涉仪,当安装了高速扫描选件后,测试速度达到0.5s是世 界上最快的,它大大提高了短波长激光二极管的产能。
光器件的准确设计以控制光输出和光反射是十分重要的。Q8341的相干分辨0.001mm,这使得Q8341成为研究下一代激光二极管的最好的选择。

Overview
The 8341 is an optical spectrum analyzer for analyzing short wavelengths from 350nm to 1000 nm. Because it adopts a Fourier spectrum system with a Michelson interferometer, the 8341 can measure the coherence. With its narrow wavelength resolution of 0.01nm * , the 8341 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 * . Finally, with its fast 0.5s * measurement speed, the 8341 is ideal for building into systems for mass production and evaluating temperature characteristics of system components.
