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
