产 品 说 明
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。
应用:
- Optical coherence tomography
- Optical metrology
- Optical measurements
特征:
- Wide optical spectrum: 140-nm FWHM
- Coherence length* of about 3.2 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.
