Boost Your Optics & Photonics Measurements

With novel light sources being developed, ranging from continuous wave (CW) to pulsed ultrafast laser systems, the number of phenomena that can be studied with optics and photonics experimental techniques is constantly increasing, and ever smaller effects and faster processes are being investigated. Striving for higher sensitivities, quicker measurements, and higher signal-to-noise ratios requires advanced signal detection and analysis.

Zurich Instruments' Lock-in Amplifiers and Boxcar Averagers empower you with the most advanced and configurable signal recovery tools for the most demanding optical experiments. Whether your signal is sinusoidal, pulsed, or a complex waveform, our instruments provide you with the best measurement tools for your application requirements.

Read on to discover how hardware and software designed to work in concert can help you reach your goals faster.

Dr. Andre Maier and Prof. Marcus Scheele

Prof. Gary Steele

Prof. Ileana-Cristina Benea-Chelmus

"We implemented a characterization method based on asynchronous optical sampling, where the UHFLI Lock-in Amplifier from Zurich Instruments plays an important role. With this technique, we can unravel the intrinsic temporal response of the developed photodetectors in the range of pico- to nanoseconds."

Andre Maier, postdoctoral researcher (left) and Marcus Scheele, principal investigator (right) - Physical Chemistry of Nanocrystals group at the University of Tübingen, Germany.

"With the HF2LI you can do all the filtering and mixing in the digital domain. That made the difference between spending half a year getting the analog setup to work and just plugging in the HF2LI and start measuring."

Gary Steele - Heads the Quantum Circuits and Mechanics research group at TU Delft.

"We characterize the sidebands with the UHFLI, leading to a huge improvement of the signal-to-noise ratio."

Ileana-Cristina Benea-Chelmus - Head of the hybrid photonics laboratory at École Polytechnique Fédérale de Lausanne.
