Wzmacniacz homodynowy (lock-in) dwukanałowy DSP (1 mHz do 102 kHz) – Saluki SE1022D
Opis
SE1022D Digital Lock-in Amplifier provides an excellent performance within its bandwidth from 1 mHz to 102 kHz. More importantly, SE1022D has dual independent input channels and dual independent high precision signal generators. Each input channel and signal generator can be used independently which means that the SE1022D is equivalent to two traditional lock-in amplifiers. Moreover, due to the twin symmetrical design, the two independent input channels and signal generators have ultra-high synchronicity, which meets the measurement requirements demanding extremely high synchronization.

Solar Cell Quantum Efficiency Detection
The quantum efficiency of solar cells is divided into two types: EQE and IQE. The test system includes dual-channel lock-in amplifier, optical chopper, monochromator and other equipments.
The detection light from the monochromator is split into two beams. One beam is converted into photocurrent and input to the channel 1 of lock-in amplifier for comparison. The other beam illuminates the solar cell, and the resulting photocurrent is measured by channel 2 of the lock-in amplifier.
The ratio of the two channel measurements, combined with the relevant formula, allows the quantum efficiency of the solar cell to be calculated.
