TRENTON, N.J., Aug. 19, 2011 — Princeton Instruments has released LightField 4.0, a 64-bit image and spectral acquisition software package that provides the functionality needed to set up and perform complex optical diagnostic experiments. It fully supports the company’s PIXIS, PI-MAX 3, ProEM, PyLoN and Quad-RO cameras as well as Acton series spectrographs, including the LS785.
The proprietary and patent-pending IntelliCal spectrograph calibration method ensures pixel-by-pixel wavelength and intensity accuracy by using NIST-traceable references. The company’s PI-MAX 3 intensified CCD cameras can be controlled through LightField via a virtual dashboard akin to a laboratory oscilloscope.
The automated IntelliCal feature enables calibration of entire spectra in both the wavelength and intensity scales against the NIST database. The spectral response of all elements in the detection path, including that of the grating and the camera, has been taken into account. The accuracy of IntelliCal calibration can be as much as 10 times better than standard calibration, the company says, allowing researchers to compare their data on absolute scales.
Researchers performing time-resolved imaging and spectroscopy will benefit from the new release. Whenever a PI-MAX 3 intensified CCD camera is connected, LightField automatically displays SuperSynchro timing and intensifier control. Users can interactively drag and adjust the gate delay, width, SyncMaster and auxiliary delays on the fly. Synchronizing the camera with external lasers is simple. The software automatically keeps track of gate delay/width information in the acquired file and, with a single click, users can quickly plot time vs. intensity graphs to gain fast insight into the process under study.
Additional features include automatic hardware detection with intelligent default setup, automatic saving of every acquisition (complete with raw data and experiment settings), direct streaming of multigigabyte pixel data to hard drive, “live vs. previously acquired” data comparison, live statistics, a search box, a spectrograph alignment helper, a built-in time stamp, multiple-user experiment settings (save/load), multiple-camera control, and customization via add-ins, automation with third-party programs, and the PICAM application programming interface. The software runs on Microsoft Windows 7 Professional and Ultimate operating systems.
