Light Conversion CARPET View Spectroscopy Data Analysis Software

Light Conversion's CarpetView is a software package dedicated for inspection, visua­lization and analysis of ultrafast spectroscopy data. It is compatible with various ultrafast spectrometers. It comes in two guises: classical view is dedicated to be used with pump‑probe and time‑resolved fluorescence datasets and 3D view is dedicated to be used with 2D electronic spectroscopy (2DES) and Fluorescence lifetime imaging (FLM) datasets.

Light Conversion HARPIA-TB: Third Beam Delivery Extension

When standard spectroscopic techniques are not enough to unravel the intricate ultrafast dynamics of photoactive systems, multi-pulse time-resolved spectroscopic techniques can be utilized to shed additional insight. Light Conversion's HARPIA‑TB is a third beam delivery unit for the HARPIA‑TA mainframe system that adds an additional dimension to typical time resolved absorption measurements. A temporally delayed auxiliary (third) laser pulse, as depicted below, can be applied to a typical pump-probe configuration in order to perturb the on-going pump-induced photodynamics.

Light Conversion HARPIA-TF Femtosecond Fluorescence Upconversion & TCSPC Extension

Light Conversion's HARPIA‑TF is a time-resolved fluorescence measurement extension to the HARPIA‑TA mainframe that combines two time- resolved fluorescence techniques. For the highest time resolution, fluorescence is measured using the time-resolved fluorescence upconversion technique, where the fluorescence light emitted from the sample is sum-frequency mixed in a nonlinear crystal with a femtosecond gating pulse from the laser. The time resolution is then limited by the duration of the gate pulse and is in the range of 250 fs. For fluorescence decay times exceeding 150 ps, the instrument can be used in time-correlated single-photon counting (TCSPC) mode that allows for measuring high-accuracy kinetic traces in the 200 ps – 2 μs temporal domain. HARPIA‑TF extension is designed around the industry leading Becker&Hickl® time-correlated single-photon counting system, with different detector options available.

Light Conversion HARPIA-TA: Ultrafast Transient Absorption Spectrometer

The popular transient absorption spectrometer HARPIA from Light Conversion, has been reimagined and redesigned to meet the needs and standards of today's scientific world. The new improved HARPIA offers a sleek and compact design and together with intuitive user experience and easy day-to-day maintenance. Adhering to the standards raised by the OPRHEUS line of devices, the entire spectroscopic system is now contained in a single monolithic aluminum casing that inherently ensures excellent optical stability and minimal optical path for the interacting beams. In contrast to its predecessor, the dimensions of the device are greatly reduced. The area was reduced roughly by 2.6x, whereas volume was reduced by nearly 4x. The new HARPIA can be easily integrated with both PHAROS / ORPHEUS and Ti:Sa / TOPAS laser systems. Just like its precursor, it features market leading characteristics such as 10-5 resolvable signals along with other unique properties such as the ability to work at high repetition rates (up to 1 MHz) when used with PHAROS / ORPHEUS system. High repetition rate allows measuring transient absorption dynamics while exciting the samples with extremely low pulse energies (thereby avoiding exciton annihilation effects in energy transferring systems or nonlinear carrier recombination in semiconductor/nanoparticle samples).

Light Conversion HARPIA: Femtosecond Extended Spectroscopic Systems

Capabilities of Light Conversion's HARPIA‑TA spectrometer can be further expanded by HARPIA‑TF and HARPIA‑TB extensions. Funda­men­tally, the all-integrated HARPIA system can be viewed as a miniaturized lab facilitating all the most popular time-resolved spectroscopy experiments in a single package. The all-inclusive HARPIA system can provide an extensive comprehension of the intri­cate photophysical and photochemical properties of the investigated samples.

Switching between different experimental realizations is fully automated and requires very little user interference. The optical layout of HARPIA system is refined to offer both an incredibly small footprint (see the dimensions below) and an easy and intuitive user experience. Despite its small size, HARPIA is easily customizable and can be tailored for specific measurement needs. All the experiments that the HARPIA system provides are managed by a new and improved user application with experiment guiding wizards, measurement presets, and develop­ment kit for custom applications.
