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.
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.
