A test platform that adapts to your needs

FPGA-based Moku devices deliver a fully reconfigurable suite of test and measurement instruments, giving you the right tool for every situation. Alongside tools crucial for optics and photonics, like the Laser Lock Box, Phasemeter, and Lock-in Amplifier, and Time & Frequency Analyzer, are test essentials such as an Oscilloscope, Spectrum Analyzer, and Waveform Generator. Run multiple instruments side-by-side in Multi-instrument Mode, or deploy your own custom algorithms with Moku Cloud Compile.

Seamless lock-in detection

Utilize the 4-channel, 600 MHz Moku Lock-in Amplifier for multiple frequencies or harmonics, and output the demodulated signal to use in a feedback loop or PLL. Achieve ultra-low noise performance with 10-bit and 18-bit blended ADCs.

Painless laser locking

Easily lock lasers to a cavity using the PDH method with the Moku Laser Lock Box, which combines the functionality of a lock-in amplifier and a PID controller. Use the Lock Assist feature to instantly lock to any zero-crossing on the demodulated error signal with a single click.

Lossless event counting

Whether you’re performing photon counting or free-space optical communications, utilize the 4-channel Moku Time & Frequency Analyzer to detect photon events, generate time interval statistics, and output histogram data — all with zero dead time.

Faster optical PLLs

The Moku Phasemeter enables you to auto-lock onto an input frequency and visualize phase, frequency, and amplitude over multiple channels, all while recording with an embedded data logger. With the ability to output phase-locked signals, your optical PLLs are so much easier to implement. Watch the video to learn more.

Engineered for demanding photonics applications

Moku:Pro delivers a range of essential optics instrumentation in one flexible, FPGA-based device. Deployed standalone or in Multi-instrument Mode, the Lock-in Amplifier, Laser Lock Box, Phasemeter, and Time & Frequency Analyzer cover applications such as:

Gravitational wave detection
Hanbury-Brown-Twiss interferometry
Laser frequency stabilization with PDH locking
Mach-Zehnder interferometry
