At the heart of this system is the CornerstoneTM 260 ¼ Monochromator with three gratings (200-1400, 450-1400, 600-2500 nm) connected by a mounting kit with a NEWPORT 300 W Xe Research Source, providing the broadband light sourse from which a certain wavelength is selected at the two exit slits of the monochromator. An Optical Power/Energy Meter (NEWPORT 1918-C) together with a calibrated UV Enhanced Silicon Photodetector (NEWPORT 918D-UV-OD3) will be used for measuring the output light of the monochromator. A solarization resistent fiber cable can be connected at one of the monochromator exit slit for measuring micrometer scale photodetectors. The measurements are based on the loch-in technique using the Stanford Research SR830 Lock-In Amplifier and SR540 Optical Chopper. The monochromator and lock-in amplifier are controled through a RS232 interface using an in-house developed software package. |
