Industry-Standard, High-Performance CCD Cameras

PIXIS series cameras are fully integrated, low-noise cameras designed for quantitative scientific imaging and spectroscopy applications from the UV to the NIR. Utilizing Princeton Instruments’ exclusive XP cooling technology, PIXIS is the only scientific camera platform that offers deep cooling with an all-metal, hermetically sealed design and a lifetime vacuum guarantee. High quantum efficiency and ultra-low-noise electronics make PIXIS cameras ideal for demanding, low-light applications such as astronomy, Raman spectroscopy, Bose-Einstein condensates (BEC), solar cell inspection, and fluorescence imaging. PIXIS cameras are available with eXcelon, which increases detector sensitivity while suppressing the etalon interference fringes typically observed in the NIR when using conventional back-illuminated devices.

PIXIS cameras include the following salient features:

  • Support for CCDs of varying sizes
  • Sensitivity from ~120 nm to ~ 1100 nm (UV to NIR) with
    eXcelon technology
  • Unique vacuum technology
  • Flexible readout design
  • High-speed USB 2.0 interface
  • Powerful 64-bit LightField software


PIXIS series cameras are fully integrated, low-noise cameras designed for quantitative scientific imaging and spectroscopy applications from the UV to the NIR.

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

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.

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.

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.

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

NIR Spectroscopy Aids in the Diagnosis of Neonatal Brain Injury
Over the past several years, biomedical researchers and engineers working in labs, hospitals, and universities around the world have developed an extensive set of spectroscopy-based methods — including a new class of noninvasive in vivo techniques utilizing near-infrared spectroscopy (NIRS) — to facilitate the rapid and accurate detection and diagnosis of disease and injury.

Advanced CCD Cameras and Imaging Spectrographs Facilitate Acquisition of Novel Femtosecond Stimulated Raman Spectroscopy Data To Improve SERS Biosensors
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
