PulseCheck Autocorrelator

The pulseCheck autocorrelator from APE is the industry leader in ultrafast pulsewidth measurement, covering pulses from 5fs to 500ps and 200nm to >12um.

The pulseCheck autocorrelator is a versatile and user friendly autocorrelation system offering a wealth of features for discerning pulse diagnostics. A special delay line allows the user to choose the scan range according to pulse duration down to 150fs, and the special all reflective optics sets are factory aligned giving easy beam handling.
