IdealPhotonics' thermal optical power meter probe utilizes a thermopile or pyroelectric effect to convert light energy into heat energy and measure the temperature rise. Through calibration, it becomes a wavelength-independent sensor capable of detecting absolute optical power across a wide spectrum (UV to far-infrared) and at high power levels (mW to kW).Features include wide wavelength coverage, high damage threshold, and stable reliability, making it suitable for high-power measurements of continuous/pulsed lasers.
