Q系列-940nm SLD宽带光源

 

 

T系列和Q系列-SLD宽带光源是极宽光谱带宽、很低相干性220V交流台式光源，以3个T系列和4个Q系列光纤耦合的SLD超辐射发光二极管模块为基础，具有略微移动的中心波长，结合适当的宽带单模光纤耦合器构成。这个SLD模块控制器设计确保光源工作极好的稳定性。

这些器件是为光学测试和测量应用而开发的。

Model number：Q-940-HP

应用：

- Optical coherence tomography

- Optical metrology

- Optical measurements

 

特征：

- Extremely wide optical spectrum

covering NIR range: 780 – 1080 nm

- Coherence length* of less than 1.5 μm (in air)

- High output power

- Low Relative Intensity Noise (RIN)

* Coherence length is determined as full width at half maximum of the coherence function plotted versus mirror displacement.
