Phase-Locked Loop Technology Heritage
Lock-in amplifiers are essential tools for extracting signal amplitude and phase information in extremely noisy environments. They play a critical role in research areas such as optics and photonics, nanotechnology, materials science, quantum technology, scanning probe microscopy, and sensor development.
Zurich Instruments brings nearly 20 years of innovation in phase-locked loop (PLL) technology, having pioneered digital PLL amplifiers with integrated feedback loops, multi-frequency measurements, sideband analysis, and arbitrary waveform generation. The VHFLI lock-in amplifier continues this legacy with higher bandwidth, lower noise, and industry-leading analog performance—making advanced signal analysis accessible to a broader range of laboratory applications.
Addressing Modern Research Challenges
Many research laboratories face challenges such as complex experimental setups, synchronization of multiple instruments, and time-consuming hardware integration. These issues can slow experimental progress and limit focus on innovation.
The VHFLI addresses these challenges by consolidating multiple measurement functions into a versatile and efficient platform. This enables laboratories to accomplish more with fewer resources, run complex experiments faster, and gain deeper insights into their measurements—supporting the freedom to innovate.
