/高功率SLD寬帶光源
D系列840nm高功率 SLD寬帶光源是很寬帶寬、低相干性、交流220V臺式光源，以兩個單模耦合的超輻射發(fā)光二極管模塊為基礎，具有略微移動的中心波長，與一個合適的寬帶單模光纖耦合器相結合構成。這個SLD模塊控制器設計確保極好的光源工作穩(wěn)定性。有和沒有防止SLD免受光反饋損傷的光隔離器的最強有力的版本都是有效的。這些器件是為光學試驗和測量應用而開發(fā)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.
