/高功率SLD宽带光源

D系列840nm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-840-HP

 

Applications:

- Optical coherence tomography

- Optical metrology

- Optical measurements

 

Features:

- Two models: optically isolated D-840-HP-I, and

D-840-HP without optical isolator for applications

with optical feedback of less than −30 dB

- Wide optical spectrum: 100-nm FWHM

- Coherence length* of less than 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.
