IdealPhotonics' visible light autocorrelation meter is a precision instrument based on the principle of optical autocorrelation. It is specifically designed to measure the temporal characteristics of ultrashort laser pulses in the visible light band (400-700 nm), acquiring information such as pulse width, shape, and chirp through pulse self-interference.Based on autocorrelation interferometry, it achieves ultra-high temporal resolution measurement of femtosecond/picosecond laser pulses in the visible light band (400-700 nm), possessing both pulse width and phase feature resolution capabilities.
