PicoQuant upgrades its multichannel event timers with flexible and powerful hardware event filters

A recent, free gateware and software update enables higher throughput and smaller data sizes for demanding applications

With the release of a free gateware and software update, PicoQuant adds a powerful, new feature to the MultiHarp 160 and 150P event timers: multifunctional on-board event filters. These user-definable filters are hardware-based and enable the filtering of events in real time. This feature is particularly aimed at demanding application scenarios that make use of information spread across several channels, such as coincidence counting in quantum sciences.

Meet Prima, PicoQuant’s new multiple color pulsed diode laser

The stand alone, compact laser module provides three individual wavelengths at an affordable price

In a recent webinar, PicoQuant has unveiled its latest laser innovation: the stand alone, fully computer controlled laser module Prima. “Our objective when developing Prima was to offer a solution to a common challenge faced by many researchers. They often need more than a single excitation wavelength to study all of their samples, but buying multiple lasers can become quite expensive. So we tapped our 25 years of expertise in laser development to create an affordable, compact module that can emit red, green, and blue light”, says Guillaume Delpont, Product Manager at PicoQuant.

PicoQuant expands its VisUV/IR laser line up

The UV and high-power laser modules are now fully remote controlled and feature a new model emitting at 1950 nm

The VisUV/VisIR laser modules from PicoQuant have undergone a few in-depth hardware changes.While the classic VisUV/VisIR laser modules were manually controlled through a series of switches and dials on the device’s front panel, devices from the new generation are now fully remote controllable via a variety of interfaces. They can be directly connected to a PC via USB interface or to a Sepia PDL 828 laser driver through a PicoQuant proprietary interface. In both cases, the laser module is fully controlled via an intuitive graphical user interface running under WindowsTM. Serial connect via an additional RS-232 interface is also available.

Additionally, two new models have joined the high-power VisIR laser series to expand its covered emission range towards the mid-infrared (MIR) at 1950 nm. Based on a novel fiber amplifier technology, these lasers can be offered with either collimated free beam or a fiber output and deliver an average output power of more than 0.5 W with pulse duration below 100 ps FWHM. The compact form factor and flexible repetition rates with constant pulse parameters make those models of particular interest for metrology and ranging measurements as well as for testing and calibration of detectors and cameras in the NIR/MIR region.

PicoQuant and Seven Solutions jointly release white paper on synchronizing TCSPC units in a White Rabbit timing network

Free paper demonstrates impact of synchronization on time accuracy of MultiHarp devices connected by switches

In a recent paper, researchers from PicoQuant have demonstrated that synchronizing Time-Correlated Single Photon Counting (TCSPC) devices in a White Rabbit timing network has only a negligible effect on their time accuracy. Multiple devices from PicoQuant’s MultiHarp product line were connected using Low Jitter White Rabbit switches from Seven Solutions the leading manufacturer of White Rabbit components. The authors have investigated how various network topologies, optical fiber lengths, and presence of Ethernet traffic affects the time accuracy of connected MultiHarp 150 and MultiHarp 160 devices.

PicoQuant improves the MultiHarp 150’s temporal resolution

Latest firmware and software updates improve the temporal resolution to 5 ps for the high-throughput multichannel event timer

PicoQuant is releasing a free firmware update for several models of its MultiHarp 150 high-throughput multichannel event timers. A major feature of this update is the improvement of the temporal resolution from 10 to 5 ps for the MultiHarp 150 4P, 8P, and 16P, without affecting other parameters like the excellent data throughput or the system's ultrashort dead time. Another new feature the update provides is a programmable input hysteresis for noise suppression in difficult environments. These MultiHarp 150 models provide the best temporal resolution on the market for event timers featuring sub-nanosecond dead time, which makes these devices an ideal choice of TCSPC electronics for fast and precise fluorescence lifetime imaging (rapidFLIM) and high throughput multichannel photon correlation.
