Products: PIXIS CCD Cameras for Imaging & Spectroscopy

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) wavelength range with eXcelon technology
  • Unique vacuum technology
  • Flexible readout design
  • High-speed USB 2.0 interface
  • Powerful 64-bit LightField software

Sensor Types:  

  • Princeton Instruments' proprietary eXcelon process increases detector sensitivity in the blue and NIR while suppressing etalon interference fringes.
  • B/I DD (Back-illuminated deep depletion) sensors have up to 95% QE in the NIR with minimal etaloning.
  • B/I (Back-illuminated) sensors have up to 95% QE in the visible but are subject to etaloning in the NIR.
  • BUV (Enhanced UV) sensors offer the highest UV sensitivity with moderate visible sensitivity.
  • F/I (Front-illuminated) CCD sensors offer economical performance from ~400-1000 nm with up to ~50% QE and negligible etaloning. Open Electrode architecture improves QE by reducing the area of the electrodes.

Pixel Size:

  • All PIXIS cameras offer 100% fill factors
  • Larger pixels offer higher well capacity
  • Smaller pixels offer higher spatial resolution in some cases; for more information, see hyperlink to IsoPlane page

Peak QE:

  • Maximum values of quantum efficiency (QE) are shown at 25° C.

 

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.

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.

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

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.
