Autocorrelator



Mini PD by APE is the Perfect Combination of Compact Size and A Single Wavelength Range


NIST Traceable Calibration

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.

Different Models for Different Wavelengths

The Mini PD is available in a selection of models, each of which covers a different wavelength range, and is ideal for routine tasks where a change in Optics Sets is not necessary.

Compact Design

With its compact footprint of only 160 x 220 x 155 mm, the Mini PD 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.

Switching Between Collinear and Non-Collinear Mode

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.

Working with the pulseLink Controller (applicable to Mini PD, Mini TPA, pulseCheck)

Acquisition Software and TCP/IP Standard Software Interface

All models come with an easy to use data acquisition software, allowing for real-time data display. Furthermore, the TCP/IP-based standard software interface by APE makes it straight forward to set up remote control. This allows you, for example, to design your own automated measurement routines. Simply use our protocol templates for rapid configuration with familiar programming languages, including C++, C#, LabVIEW, Python, Matlab, and Ruby.
