At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.

Alternatively, fluorescent samples can be analysed using Femtosecond Optically Gated (FOG) lifetime methods. A tuneable ca. 100 fs ‘pump’ pulse is used to excite the sample, and the resulting emission is mixed with a second ‘gate’ pulse in a non-linear crystal, yielding an upconverted signal and providing the best available time resolution. Using this technique, fluorescence lifetimes with femtosecond time resolution can be obtained. Longer lived samples (> 2 ns) can be analysed using more traditional Time Correlated Single Photon Counting (TCSPC) approaches.

Noncontact optical linear encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement.

Ultrafast spectroscopy is used to measure the kinetics for a variety of important photophysical processes in chemical and biological research, including electronic structure, photoisomerizations, energy and/or electron transfer, charge transport, optical non-linear effects, and many other processes.

In TA spectroscopy, a tuneable ca.100 fs ‘pump’ pulse is used to initially populate higher energy excited states. A second ‘probe’ white light pulse is then used to measure the differential absorption of these species. Detection wavelengths currently available span the Visible (420-810 nm) and Near Infra-Red (850-1600 nm) regions. Using a continuum based white light source, we are able to extend the detection time window from ~200 fs (FHWM IRF) to ~1 msec.
