Multiple Monochromator Measurements
Procedure
| E305SL surface mount UV LED by International Light Technologies
Using Vsource = ILED Rseries + VLED, where in this case, ILED=20mA and VLED=5.5V, the resistor was chosen to be 150 ohms and the source voltage was set to be 8.5V.
Measured Vsource = 8.59 V, measured VLED = 4.15V.
The monochromator was power cycled between each measurement.
Background Measurement
Fluctuations about Position
With current methodology, measurements are quite inconsistent.
LED Measurement
The LED was placed (10.0 +/- 0.5) cm away from the face of the monochromator.
