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 LF5: 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 LF5:
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 LF5:
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 LF5: 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 LF5:
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 LF5: 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 LF5: 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 LF5: 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.

Tip-Enhanced Raman Spectroscopy
TERS - Tip-Enhanced Raman spectroscopy

X-Ray Plasma Diagnostics
Hot and dense plasmas are of enormous interest in basic physics research because of the multitude of interesting phenomena that arise from them.

Laser-Induced Breakdown Spectroscopy
LIBS is considered one of the most convenient and efficient analytical techniques for trace elemental analysis in gases, solids, and liquids. LIBS spectra obtained by the Mars Curiosity Rover have confirmed that our sister planet could have harbored life

Absorbance, Reflectance and Transmission
A measure of the amount of light absorbed by a sample as a beam of light passes through it.

Fluorescence, Phosphorescence, and Photoluminescence Spectroscopy
Fluorescence, phosphorescence and photoluminescence occur when a sample is excited by absorbing photons and then emits them with a decay time that is characteristic of the sample environment.

Coherent X-Ray Diffraction
X-ray diffraction is a technique for studying the characteristics of matter such as macromolecules, crystals, powders, polymers, and fibers.

Small Animal Imaging
For small-animal imaging in the NIR II / SWIR range, Princeton Instruments recommends the NIRvana:640 camera. We designed this 16-bit camera specifically for scientific research applications that require superb linearity and excellent near-infrared sensitivity.

Astronomical Imaging
Astronomical imaging can be broadly divided into two categories: (1) steady-state imaging, in which long exposures are required to capture ultra-low-light-level objects, and (2) time-resolved photometry, in which integration times range from milliseconds to a few seconds.

General Raman
The most common application of Raman spectroscopy involves the vibrational energy levels of a molecule. Incident laser light in the UV, visible or NIR, is scattered from molecular vibrational modes.

Surface-Enhanced Raman Spectroscopy
SERS - Surface-enhanced Raman spectroscopy

Bose-Einstein Condensate
Bose-Einstein condensate (BEC) can be regarded as matter made from matter waves. It is formed when a gas composed of a certain kind of particles, referred to as “bosonic” particles, is cooled very close to absolute zero.

Coherent Anti-Stokes Raman Spectroscopy
Coherent Anti-Stokes Raman spectroscopy (CARS) a type of non-linear Raman spectroscopy. Instead of the traditional single laser, two very strong collinear lasers irradiate a sample.

Soft X-Ray Microscopy
Soft X-ray Microscopy is used for imaging and researching the elemental composition and structure of biological samples and more.

Singlet Oxygen Imaging
Singlet oxygen, the first excited state of molecular oxygen, is a highly reactive species that plays an important role in a wide range of biological processes, including cell signaling, immune response, macromolecule degradation, and elimination of neoplastic tissue during photodynamic therapy.

Combustion researchers rely on laser-based optical diagnostic techniques as essential tools in understanding and improving the combustion process.

Nanotechnology helps scientists and engineers create faster electronics as well as ultrastrong and extremely light structural materials.

EUV Lithography
EUV lithography is gaining popularity because it retains the look and feel of the traditional optical lithography process (i.e., utilizes the 13.5 nm wavelength) and uses the same basic design tools.

FLIM - Fluorescence Lifetime Imaging Microscopy
FLIM encompasses several techniques for mapping the spatial distribution of excited-state lifetimes of emitting molecular species with nanosecond and microsecond temporal resolution.

Dynamic Neutron Radiography
Neutron radiography offers an excellent complement to x-ray imaging for a diverse range of nondestructive investigations

Plasma Emission Spectroscopy
The different types of plasma emission spectroscopy can be categorized by how the plasma is generated. Spectra of nuclear fusion plasmas are used to ascertain the chemical species present and other properties.

Resonance Raman Spectroscopy
Instead of fluorescence, some types of colored molecules produce strong Raman scattering at certain conditions. This effect was called Resonance Raman.

X-Ray Spectroscopy
X-ray absorption spectroscopy is an element-specific probe of the local structure of elements in a material.

Stimulated Raman Scattering
Stimulated Raman scattering takes place when an excess of Stokes photons that were previously generated by normal Raman scattering are present or are deliberately added to the excitation beam.

Streak Tube Readout
Streak tube readout is commonly used to obtain intensity vs. spatial or spectral information over time periods of picoseconds to nanoseconds.

Micro-Computed Tomography
Micro Computer Tomography is a unique technique for the noninvasive, nondestructive 3D characterization of materials down to a micrometer scale.
