产 品 说 明
D系列890nm高功率 SLD宽带光源是很宽带宽、低相干性、交流220V台式光源,以两个单模耦合的超辐射发光二极管模块为基础,具有略微移动的中心波长,与一个合适的宽带单模光纤耦合器相结合构成。这个SLD模块控制器设计确保极好的光源工作稳定性。有和没有防止SLD免受光反馈损伤的光隔离器的最强有力的版本都是有效的。这些器件是为光学试验和测量应用而开发的。
Model number:D-890-HP
Applications:
- Optical coherence tomography
- Optical metrology
- Optical measurements
特征:
- Wide optical spectrum: 150-nm FWHM
- Coherence length* of less than 3 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.
