The LBTEK SFPI-C Fabry–Perot Interferometer Driver generates precision voltage signals to drive piezoelectric transducers (PZTs), enabling accurate control of the mirror spacing within a confocal Fabry–Perot (F-P) cavity.
The front-panel LCD touchscreen allows intuitive adjustment of output parameters. Its frequency zoom function provides 11 selectable scaling levels (1×, 2×, 4×, etc.), enabling users to fine-tune the scanning frequency for enhanced spectral resolution.
The driver also includes a TTL trigger output, supporting external oscilloscope synchronization, and a 4-level adjustable high-precision photodetector amplifier circuit for monitoring the cavity transmission signal in real time.
