The APE Mini Autocorrelator is the perfect combination of tuning-free autocorrelation measurement, compact size and high sensitivity.
The Mini autocorrelator is an ideal solution for measuring the pulse duration of laser systems with pulse duration from a few femtoseconds (fs) up to a few picoseconds (ps) and with any repetition rate. It is available for different wavelength ranges, easy to adjust and to handle.
With its compact footprint of only 160 x 220 x 155 mm, the Mini autocorrelator is perfect for working environments where space is limited. When it is needed elsewhere, simply place this portable unit in the lightweight aluminum case provided, for easy and safe transportation to the next site.
APE provides a selection of exchangeable Optics Sets, ranging from UV at 250 nm to IR at 3200 nm, for sensitive measurements across an extremely broad wavelength region. Due to its compact footprint, the Mini TPA is also the perfect answer to your space-saving and easy portability requirements.
