Q系列-940nm SLD寬帶光源
T系列和Q系列-SLD寬帶光源是極寬光譜帶寬、很低相干性220V交流臺(tái)式光源,以3個(gè)T系列和4個(gè)Q系列光纖耦合的SLD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,結(jié)合適當(dāng)?shù)膶拵文9饫w耦合器構(gòu)成。這個(gè)SLD模塊控制器設(shè)計(jì)確保光源工作極好的穩(wěn)定性。
這些器件是為光學(xué)測(cè)試和測(cè)量應(yīng)用而開發(fā)的。
Model number:Q-940-HP
應(yīng)用:
- Optical coherence tomography
- Optical metrology
- Optical measurements
特征:
- Extremely wide optical spectrum
covering NIR range: 780 – 1080 nm
- Coherence length* of less than 1.5 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.
