Presentation Transcript


1. QE65000 Highlights Slits Included in price Gratings H1-H14 HC1 cost extra Filter Only OFLV-200-1100 available in 3 weeks cost extra No L2 lens Detector Low noise S7031-1006 Back thinned - 90% QE 2-D structured array TEC Cooled Spectrometer USB 2.0 interface 16 bit ADC Low noise electronics Other features

2. QE65000 Resolution

3. S7031 Detector Pixels 1024x58 (active) 24um square 1044x64 (total elements) 24.5 x 1.39mm Active area No dark pixels Sensitivity 2.2uV/e Well depth 300Ke individual ~1.5Me summing Low noise Dark Signal ~200e/pixel/s @ 0C Readout noise 16e

4. QE65000 Spec’s USB 2.0 Interface Transfer scan <1ms Integration time 7ms to 15min A/D: 16 bit 500KHz TEC 40C below ambient -5 to –15C 0.1C resolution & stability Triggering: Only software No External Hardware Trigger or External Synch Strobe Signals (fully programmable) Single Strobe Continuous Strobe GPIO: 10

5. QE65000 Spec’s Noise Readout noise: 1.2 counts rms (36 e) Dark signal: 2.5 counts rms @ int times <100ms 25 counts rms @ 5 min Dynamic Range 25000:1 S/N ~ 1200:1 (well depth) Dark Signal Double/halves for every ~6C ~30 counts/pixel/sec @ -15C Integration time to half well is 1000s or ~16min

6. QE65000 Dark Characteristics

7. QE65000 Sensitivity Up to 90% QE Sony is at best 40% QE and ~4% in UV Sensitivity 30 e/count 0.03 counts/e 21 photons/count

8. QE65000 Sensitivity

9. QE65000 Linearity Non-Linearity Very good ~1% Corrected Non-Linearity ~0.25%

10. Software

11. QE65000 Application Strengths Long Integration Time For stationary signals/samples Use QE65000 >20 sec Use USB2000 <20 sec Constrained applications Use QE65000 if they can’t average more to increase S/N If the sample is moving and they only have 1 shot

12. QE65000 Etalon Effect Etalon present 800-1000nm Caused by passivation ontop of detector Normalizable if Detector Temp constant

13. Competitors
