TCSPC and Time Tagging Electronics

We offer a wide range of Time correlated single photon counting devices for varying applications including, single molecule spectroscopy, Time resolved Fluorescence and much more. For more information please contact our experts.

We offer several modules for Time-Correlated Single Photon Counting (TCSPC), Multi-Channel Scaling (MCS), coincidence correlations, or event timing with temporal resolutions between picoseconds and milliseconds. Single channel as well as multichannel versions with either USB or PCIe interface can be provided high quality and reliability.

Time-Tagged Time-Resolved (TTTR) mode allows the recording of individual count events directly to hard disk or computer memory. The timing of each photon is captured as an event record without any early data reduction (such as on-board forming of histograms). This mode is particularly interesting where, e.g., the dynamics in a fluorescence process are to be investigated in depth. The availability of the full timing information permits photon burst identification, which is of great value, e.g., for single molecule spectroscopy in a liquid flow. Other typical applications are Fluorescence Correlation Spectroscopy (FCS) and Burst Integrated Fluorescence Lifetime (BIFL) measurements.

The PicoQuant group was founded in 1996 to develop robust, compact, and easy to use time-resolved instrumentation and systems. Since April 2008 sales and support in North America is handled by PicoQuant Photonics North America Inc. In January 2010, the PicoQuant group was extended by PicoQuant Innovations, which was founded to support the increasing activities in the field of teaching, customer support, and event organization.

Today, PicoQuant is known as a company leading in the field of pulsed diode lasers, time-resolved data acquisition, single photon counting, and fluorescence instrumentation. In 2002, they developed the first commercial ultrasensitive fluorescence microscope that permits measurements on the single molecule level. Their instruments are used all over the world. They help to prepare papers in high-ranking journals as well as carrying out routine quality control and production processes of global industrial players. Starting from traditional time-resolved fluorescence detection in bioanalytics, the range of applications is continuously increasing and includes semiconductor quality control, diffuse optical tomography, quantum information processing, optical detector testing, and telecommunications. Due to their easy to use products, researchers can now focus on their problems in biology, medicine, environmental science, or chemistry without needing a large background in physics, electronics, or optics.

What's New?

We’ve recently refreshed our website, and we hope that you will find the changes to be a big improvement. We’ve worked hard to make it easier to navigate the site, and to find exactly what you need from among our vast and diverse range of products.

Missing e-commerce?

One thing that we’ve not carried over from the previous site at this time is the facility to order online for a select range of our products, which you may have been used to in the past. “Off-the-shelf” items represent a small part of our product range; most often a purchase requires a more in-depth discussion between our sales team and the customer to match the right product to the user’s application. For this reason we have focussed on making it as easy as possible to request a quotation from our sales team.

Please rest assured that we will get back to you with pricing promptly, and will work with you to make sure the products you buy are exactly what you need. Once you’re ready to order, our sales team will work through the process with you, to make it as seamless as possible.

Once you’ve selected all the items you’re interested in, by clicking “Add to Quote” on the product page, just click “View Quote Request List” or the icon in the top navigation bar, check your list, set quantities, complete your details and submit the form. Our sales team will respond by email, in a timely manner.

If you have any other questions in the meantime, please get in touch directly.
