PowerMax-Pro USB/RS Sensors

New PowerMax-Pro incorporating LabMax-Pro instrumentation directly within the sensor cable.

PowerMax-Pro USB and RS sensors incorporate LabMax-Pro instrumentation directly within the sensor cable. Similar to other Coherent USB and RS sensors, this configuration offers a smaller form factor for use inside laser processing systems or production lines. Additionally, the cost of annual calibration is half that of a separate meter and sensor system. The PowerMax-Pro USB and RS sensors operate with LabMax-Pro PC applications software (included).

PowerMax-Pro USB and RS Sensors

PowerMax-Pro (Patent #9,012,848) represents a dramatic technological advancement in laser power sensing that utilizes a thin-film detector only microns thick which rapidly senses thermal changes due to incident laser energy. The result is a measurement response time below 10 μs, as compared to over 1 second for traditional thermopiles. These detectors can operate at high power over a spectral range as broad as 300 nm to 11 μm, and incorporate a large 30 mm x 30 mm active area.

The high response speed of PowerMax-Pro sensors is particularly advantageous in a wide range of commercial and medical applications. It enables nearly instant measurement of CW laser power, resulting in increased throughput, and also supports high-resolution analysis of modulated laser pulse shapes resulting in improved laser characterization and process control.
