Since the beam has been chopped at constant frequency by a rotating mechanical chopper C, this signal is an alternating current that is amplified by the lock-in amplifier A, controlling the pen of the chart recorder R. To scan the spectrum, M4 is rotated by the drive mechanism DM, which...
In Figs.5a, b, an exponential graph has been illustrated to simplify the spectral relationship between electron energy and sun radiation in UV–Vis-IR spectrums. Here, the total energy of sunlight is classified into UV–Vis-IR spectrums: UV band, 200–400 nm stores 5% of the total energy...
For each simulation under sweep parameter with respect to the wavelength from 650 to 1000 nm, then the phase spectrum was obtained. We linearly fit the phase spectrum of each element to obtain the group delay. To improve the achromatic performance, the achromatic metalens elements should have ...
