For multi-exponential reconvolution the EasyTau 2 software is an ideal tool.

It is connected to a PC through a USB 2.0 interface.

The high quality and reliability of the PicoHarp 300 is expressed by a unique 5-year limited warranty.

It allows a forward start-stop operation even at full repetition rate of mode locked lasers with stable repetition rate up to 84 MHz.

Experiments with low repetition rate benefit from the PicoHarps multi-stop capability.

The design allows high measurement rates up to 10 million countssec and provides a highly stable, crystal calibrated time resolution of 4 ps.

The instruments timing resolution is well matched to even the fastest detectors currently available: the SPAD detectors of the PDM series or micro-channel plate Photomultiplier Tubes (MCP).

Both input channels are equipped with Constant Fraction Discriminators (CFD), sensitive on the falling edge.

This unique feature eliminates the need for specially adapted cable lengths or cable delays for different experimental set-ups.

TTTR data can be correlated in real-time for monitoring of FCS experiments at count rates up to 500.000 countssec.

External marker signals can be used to synchronize the device with other hardware such as scanners, e.g., for Fluorescence Lifetime Imaging (FLIM).

In TTTR mode, the PicoHarp 300 can also be used as a generic event timer, e.g., for Satellite Laser Ranging (SLR).

Each router channel includes an internal adjustable delay with 8 ns range at 4 ps resolution to tune for relative delays.

External hardware such as monochromators can be controlled via CAN or serial bus (currently supported: Sciencetech 9030, Sciencetech 9055, Acton Research SP-2155 and Acton Research SP-275).

This is done by splitting an electrical signal from a pulse generator and feeding the two signals each to a separate input channel.

The differences of the measured pulse arrival times are calculated along with the corresponding standard deviation.

This latter value is the rms jitter which we use to specify the timing precision.

However, calculating such a time difference requires two time measurements.

Therefore, following from error propagation laws, the single channel rms error is obtained by dividing the previously calculated standard deviation by 2.

We also specify this single channel rms error here for comparison with other products.

However, no responsibility is assumed for possible inaccuracies or omissions.

Specifications and external appearances are subject to change without notice.

Important measurement characteristics such as count rate, count maximum, position and peak width are displayed continuously.

A comprehensive online help function shortens the users learning curve.

A library for custom programming, e.g., with LabVIEW is also available as an option.

Software upgrades for extended functionality will be available with further product development.
