Some examples of applications/use cases related to the functionalities and upgrade options of the instruments:
Each of these functionalities can be controlled through LabOne®, a proprietary software of Zurich Instruments. This platform-independent instrument control tool provides users with a powerful and intuitive user interface, together with support for the most popular programming languages.
These features make Zurich Instruments' lock-in amplifiers extremely versatile, allowing them to be tailored to any experimental setup, reducing experiment complexity and decreasing the time to publication.
When setting up an optical experiment, a key parameter to select is typically the frequency at which the excitation light is modulated. As a rule of thumb, and whenever feasible, it is advisable to choose a modulation frequency that is as large as possible — e.g., half the repetition rate of a pulsed laser — to minimize the impact of correlated and 1/f noise contributions.
The graphic below gives an overview of Zurich Instruments' lock-in amplifiers and the frequency range they can cover. Each instrument is capable of measuring at frequencies spanning from DC to the maximum frequency indicated on the axis.
Three reasons to choose Zurich Instruments for your optics and photonics experiment:
Explore higher frequency domains of your optical experiment with high noise rejection and faster measurements: with signal inputs up to 8.5 GHz, Zurich Instruments’ lock-in amplifiers cover a wide range of modulation techniques and applications.
Carry out multiple tasks in parallel with one instrument: for example, you can simultaneously perform lock-in detection and boxcar averaging on the signal from the photodetector while running a PID/PLL control loop to stabilize your laser cavity. The parallelization of several experimental aspects allows you to achieve results more efficiently and quickly.
- Ease of integration: thanks to our APIs (LabVIEW, MATLAB, Python, .NET, C), swiftly connect your lock-in amplifier with all the elements, e.g., delay lines and/or modulators, in your experimental setup.
