OPM150 10kHz Base Module BNC

At the heart of the 10kHz Base Module BNC is an electrical transimpedance amplifier that converts the photocurrent of the connected OPM150 detector head into a precise voltage signal. Five gain stages from 1kV/A to 10MV/A cover a wide dynamic range, from strong to very weak optical signals.

This lets you adapt the module to your application: low gain for high optical power, high gain for weak signals. The result is a clean signal with ±1% accuracy across the entire measurement range.

USB and BNC: Two Interfaces, Maximum Flexibility

The 10kHz Base Module BNC gives you two ways to use your measurement data:

USB interface: The module is both powered and controlled via USB. Connect it to your PC and the measurement system is ready immediately. No external power supply, no extra cabling, no clutter on your optical table.

Analog BNC output: The analog voltage output via BNC lets you connect the module directly to an oscilloscope, a data acquisition system or a lock-in amplifier. This makes the 10kHz Base Module BNC ideal for integration into existing test setups and automated measuring stations.

Fast Sampling for Dynamic Measurements

In standard modes, the module samples at 30 S/s, which is well suited to stable, long-term power monitoring. For faster processes, the fast sampling mode delivers 600 S/s. Combined with the 10 kHz measurement bandwidth, the 10kHz Base Module BNC captures both slow drifts and quicker changes in optical power.

Built-in averaging helps reduce noise, while the graphical and digital display modes give you a clear view of your data in real time.

Suitable for CW and Pulsed Light Sources

The OPM150 10kHz Base Module BNC works with continuous wave (CW) light sources as well as pulsed sources above 300 kHz. This makes it a versatile tool for laser characterization, fiber optics, photonics research and quality control in production.

Robust Housing with Excellent EMI Shielding

The housing of the 10kHz Base Module BNC is milled from solid material. This construction makes it very robust and provides effective shielding against electromagnetic interference (EMI), which is a decisive advantage for sensitive measurements at high gain settings.

Two threaded holes in the base allow secure mounting on optical tables, breadboards or inside test equipment. With dimensions of only 60 × 81 × 36 mm, the module fits into even the tightest setups.

Typical Applications

The 10kHz Base Module BNC is used wherever precise optical power measurement matters:

• Laser power monitoring in labs and production
• Fiber optic measurements and component testing
• Photonics research and development
• Integration into automated test systems via BNC
• Long-term stability measurements of light sources
• Educational and university laboratories
