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.
