TruePower – Absolute Laser Power Determination

Real Values in Real-time: Automated Laser Power Determination in mW

TruePower is a new experience in laser power adjustment for confocal Raman imaging measurements. The absolute laser power is measured in the optical fiber and can be adjusted with accuracy of <0.1 mW. A laser shutter shields the sample from the laser light and opens only during Raman analysis with optimized laser power to avoid any sample degradation. TruePower is the only laser power measurement system on the market to provide such an accuracy ensuring optimal laser power for the preservation of delicate samples and reproducibility in measurement conditions.
