What sets HARPIA apart? It's the flexibility! This system is built around the HARPIA-TA transient absorption spectrometer, but it's not a one-trick pony. You can easily add time-correlated single-photon counting, Kerr gate, or fluorescence upconversion modules to boost your capabilities. And with third beam delivery and microscopy options, you'll be able to tackle even the toughest experiments. Plus, HARPIA's designed for seamless switching between measurement modes, so you can work efficiently and effectively. And to top it all off, each module is housed in a sturdy, monolithic aluminum body for maximum optical stability and minimal optical path lengths. Pair HARPIA with a PHAROS or CARBIDE laser, and ORPHEUS series OPAs for a single-supplier solution that simplifies your workflow.
