Thorlabs' expanding line of optical power and energy meters includes a large selection of sensor heads, single- and dual-channel power and energy meter consoles, power and energy meter interfaces, a wireless power meter with a built-in photodiode sensor, and a fiber optic power meter designed for use in the field. The consoles (PM100A, PM100D, PM400, and PM5020) when paired with our extensive line of power and energy sensors provide calibrated (NIST traceable) measurements across a broad range of powers, energies, and wavelengths. Our most popular consoles and sensor pairings can be purchased as bundles. The sensor calibration data is stored in the sensor head and is automatically read by the console, which allows the user to use multiple sensors with the same console. Compatible sensors are easily identified by the red C-series connector. All of our old A/B-Type sensors are available with the new connector; plus, we have continued to expand our power and energy sensor product lines.
