IdealPhotonics' dual-channel benchtop optical power energy meter integrates dual detector interfaces and a high-precision ADC module. This benchtop instrument can simultaneously measure the power (nW-kW) or pulse energy (μJ-J) of two independent optical signals (such as reference light and test light), and achieve real-time normalization detection through ratio calculation to eliminate light source fluctuation errors.Synchronous dual-channel high-precision measurement, wide dynamic range, support for multi-wavelength and pulse/continuous light analysis, equipped with a large-screen display and data interface, suitable for laboratory-level multi-optical path comparison and long-term monitoring.
