Get up and go
LightField is smart. Just connect your Princeton Instruments camera or spectrograph, launch LightField, and you're ready to start capturing data. It's that simple! LightField gives you control of key functions right from the photo-realistic graphical interface — an unparalleled user experience!
New in LightField: The improved "smart search" function quickly directs you to the controls you want as you are typing. You can even build your own custom settings dock to access frequently used settings.
Peace of mind
We understand how important your data is. LightField automatically saves every acquisition to your chosen folder and keeps track of all experiment settings in the file header. It even saves your raw data when the post-processing feature is applied.
New in LightField:
LightField can automatically export data into your favorite file format as you acquire it... TIFF, FITS, ASCII, AVI, IGOR, and Origin, just to name a few!
The power of math
New in LightField:
LightField includes a powerful built-in math engine to analyze image and spectral data in real-time. Simple math functions to complex Fast Fourier Transform (FFT) can be applied to live or post-acquisition data. The math engine even includes out-of-the-box measurements such as absorption, reflectance, and transmission, as well as an easy-to-use editor to create your own formulas.
LightField knows you
New in LightField: Often, Princeton Instruments cameras and spectrographs are used by multiple researchers in the same lab. LightField provides an easy "experiment setup" save/load function that quickly loads your experiment settings for you. Simply bring up the data file to apply the same system settings that were used previously.
Repeating experiments could not be easier!
The power of spectral calibration — IntelliCal
LightField fully supports our patented IntelliCal® spectral calibration system. Utilizing compact wavelength reference and NIST-traceable radiometric reference light sources, and easy to use work flow in LightField, you can achieve up to 10x more wavelength accuracy and intensity calibration that is free of instrument/optics bias.
Traditional spectral calibration approaches can be plagued by a host of spectral artifacts. Our intensity calibration routine automatically corrects these artifacts for the broadest spectral range.
Friend of LabVIEW® and MATLAB®
New in LightField:
Does your lab rely on LabVIEW or MATLAB to control and coordinate various pieces of experiment hardware?
LightField allows seamless integration of hardware controls and direct data acquisition into National Instruments' LabVIEW and MathWorks' MATLAB. No need to master the complexity of hardware control. LightField comes with easy-to-use examples that you can utilize right away!
Intensified CCD cameras and LightField — a match made in heaven
When users first encounter LightField's ICCD camera interface — inspired by a simple "oscilloscope" display — the reaction is nothing short of amazement.
Simply drag and adjust the gating width/delay or design entire time-resolved experiments graphically.
Streams of data in many formats — even when you're not there
Thanks to its native 64-bit architecture, LightField is not only able to utilize all the memory (RAM) available on your computer, it can stream multi-gigabyte pixel data directly onto the hard drive — all without missing a beat.
New in LightField: LightField can automatically export data as you acquire into your favorite format automatically: TIFF, FITS, ASCII, AVI, IGOR, and Origin, just to name a few!
New in LightField: LightField can send you periodic email updates — very useful if you are running an unattended extended experiment.
Compare and contrast
LightField takes data review to a new level. With intuitive controls for spectral overlay, peak find, view, and playback, it is now easier than ever to look back at your data.
New in LightField: When you need to review multitudes of images or spectra, a "synchronized" view allows you to quickly compare the same region or peak in two or more datasets.
Powerful, yet easy to use
No marketing hyperbole here.
LightField allows complete control of Princeton Instruments cameras and spectrographs.
All available readout modes are supported: frame transfer, kinetics, spectra kinetics (microsecond time resolution), and custom chip (>10 kHz frame rates).

In addition, using LightField enables 1kHz frame rates from a PIXIS 100B camera to maximize signal to noise for Femtosecond Stimulated Raman Spectroscopy (FSRS).”
"We are using the PIXIS camera and an Acton Spectrograph to analyze gases in the atmosphere though UV/Visible spectroscopy. Measurements are made for many hours at a time so we use an Add-In to the LightField software for our data acquisition which allows us to easily start our experiment and save the data to multiple files without user intervention."
“Unsere Fachgruppe am LTTT beschäftigt sich mit der Weiterentwicklung und Applikation von optischen (Laser-) Messtechniken mit besonderem Schwerpunkt auf der Analyse und Optimierung der gesamten motorischen Wirkkette. Die intuitive Bedienbarkeit und die individuelle Anpassungsmöglichkeit der Software Lightfield erlaubt uns eine schnelle und einfache Datenaufnahme an unseren vielfältigen Experimenten. In der Kombination mit PI-MAX4-Kameras profitieren wir dabei besonders vom [PI-MAX4] SuperSynchro timing-Generator, so dass eine sehr präzise zeitliche Steuerung mittels Lightfield möglich ist.”

“We use the Princeton Instruments Lightfield software to control our PI-MAX and PIXIS cameras and an Acton spectrometer. These are used for optical spectroscopy with the laser-heated diamond anvil cell at our synchrotron beamline. For this application we need to control Lightfield from the EPICS beamline control system, which has worked very well.” -Mark Rivers, Advanced Photon Source, Argonne National Laboratories, USA

Accurate characterization of surface-enhanced Raman spectroscopy (SERS) biosensors, fluorescent dye molecules that hold great promise for in vivo bioanalyte detection, can often be quite difficult as the overwhelming isoenergetic fluorescence signal typically makes it challenging to measure resonance Raman cross-sections for the molecules. To overcome this obstacle, researchers at the University of Minnesota in Minneapolis recently utilized etalonbased femtosecond stimulated Raman spectroscopy (FSRS), a technique designed to acquire a stimulated Raman signal without strong fluorescence or interference from signals resulting from other four-wave mixing pathway
