D系列890nm高功率 SLD寬帶光源是很寬帶寬、低相干性、交流220V臺(tái)式光源，以兩個(gè)單模耦合的超輻射發(fā)光二極管模塊為基礎(chǔ)，具有略微移動(dòng)的中心波長(zhǎng)，與一個(gè)合適的寬帶單模光纖耦合器相結(jié)合構(gòu)成。這個(gè)SLD模塊控制器設(shè)計(jì)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(qiáng)有力的版本都是有效的。這些器件是為光學(xué)試驗(yàn)和測(cè)量應(yīng)用而開發(fā)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.
