IdealPhotonics' power meters and energy meters are precision instruments for measuring optical signal intensity (continuous/pulse). They achieve accurate measurement of optical power (accuracy ±1%) and single-pulse energy (resolution 0.1pJ) using either a thermopile (power range 1nW-10kW) or a photodiode (response time <1ns). These are suitable for optical energy monitoring and calibration in laser processing and optical communication systems.The "Full-Range Optical Energy Scale from Picowatts to Megawatts" utilizes multi-sensor fusion technology (thermopile + photodiode, dynamic range up to 120dB) and real-time temperature drift compensation (stability ±0.2%/year). It achieves accurate measurement of all parameters from continuous laser (accuracy ±0.5%) to ultrafast pulses (pulse width 1ps-1s, energy repeatability ±1%), providing a laboratory-grade benchmark for high-power laser weapon development and optical communication module calibration.
