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.

Laboratories and manufacturers are often faced with systematically establishing an unbroken chain of calibrations to specified references. All APE autocorrelator models are calibrated to a traceable standard in accordance with NIST (U.S. National Institute of Standards and Technology) measurement traceability specifications. A printed and signed calibration certificate is provided with each pulseCheck.

Conventionally, autocorrelators used to split an optical pulse into two replicas and recombine them for the Second Harmonic Generation (SHG) in a nonlinear crystal. The APE Mini TPA instead benefits from the two photon absorption principle. This eliminates the need of SHG crystal angle tuning and makes the wavelength tuning process unnecessary.

The Mini PD supports quick and easy switching between collinear and non-collinear measurement modes. While collinear mode provides pulse width measurement with additional qualitative information about the chirp, non-collinear mode gives background-free autocorrelation with a high dynamic range.

Together with an UV Optics Set, the Mini TPA provides simple pulse width measurement in the UV range, from 250 nm to 400 nm — without the need for cross-correlation. Elimination of the cross-correlation approach also makes the data evaluation easier, by cutting the conventional two-step process to a single-step solution.

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.
