Demo Code for PHLib Programming Library for PicoHarp 300

Version 2.3
PicoQuant GmbH - April 2009


The PicoHarp 300 is a TCSPC system with USB 2.0 interface. The system requires a 686 class PC with USB 2.0 host controller, 512 MB of memory and at least 1 GHz CPU clock. The PicoHarp software is suitable for Windows 2000, XP and Vista, including the x64 versions. The programming library is a DLL with demos for various programming languages. Please refer to the manual for instructions.

New in version 2.3

  • measurement time up to 100h
  • new warnings retrieval functions
  • bugfix for T2 mode
  • demos for C#


Do not connect the PicoHarp device before installing the software.

Before installation, make sure to backup any work you kept in previous installation directories and uninstall any older versions of PHLib. The PHLib package can be distributed on CD, via download or via email. The setup distribution file is setup.exe. If you received the package via download or email, it may be packed in a zip-file. Unzip that file and place the distribution setup file in a temporary disk folder. Start the installation by running setup.exe before connecting the PicoHarp device. On some versions of Windows you may need to log on as administrator.

The setup program will install the programming library including manual, and programming demos and the device driver for the PicoHarp. The setup program will copy the device driver but it will not immediately load it. This is done by the regular Windows Plug&Play device management when you connect the device. Dependent on the version of Windows you may be prompted again at this stage in oder to confirm the driver installation.

To uninstall the PHLib package, you may need to be logged on as administrator. Backup your measurement data before uninstalling. From the start menu select: PicoQuant - PH300-PHLib v2.x > uninstall. Alternatively you can use the Control Panel Wizard 'Add/Remove Programs' (in some Windows versions this Wizard is called 'Software')
