Scanning autocorrelator IRA-3-10 Pulse duration range 30 fs - 50 ps * Wavelength range 3-10 µm * USB connection and software * Application: - Femtosecond and picosecond OPA pulse duration and near contrast measurement View software screenshot Print version  Download .pdf IRA-3-10 zoom in    The IRA-3-10 autocorrelator is specifically developed for measuring pulse duration and near contrast ratio of IR ultrafast radiation (wavelength 3–10 µm) that is usually generated by the ultrafast OPAs.    The IRA includes opto-mechanical assembly and electronics with USB interface. System is easy to operate and includes a full set of user friendly software tools for data collection and analysis. Approximation with Gauss and Sech2 profile is also available. The opto-mechanical assembly consists of optical box and mechanical kit for additional delay of reference pulse.    The acquisition and analysis software is fully compatible with Windows XP, USB drivers are included.
