Every day Princeton Instruments' PyLoN cameras play a key role in revolutionary research performed in leading labs around the world. These compact cameras include all the essentials for tackling demanding dark noise-limited imaging and spectroscopy applications.

PyLoN, which  has dark current levels on the order of 1 e-/pixel/hour, is ideal for photon-starved applications requiring long exposure times from minutes to hours such as tip-enhanced Raman spectroscopy (TERS), astronomy and photoluminescence.

NIR fluorescence spectra

NIR fluorescence spectra.

The PyLoN camera supports high-resolution front-illuminated (F/I), back-illuminated (B/I), and back-illuminated deep-depletion (B/I DD) imaging and spectroscopy CCDs. Every PyLoN camera delivers the highest sensitivity, lowest noise and highest dynamic range in its class.


Sensitivity from ~ 120 nm to
 ~ 1100 nm:
  • Broadest wavelength coverage for the widest variety of applications
  • > 95% quantum efficiency (QE) with selected CCDs
  • High QE in UV with UV enhanced CCD or Unichrome / Lumogen phosphor coating
  • Enhanced sensitivity and reduced etaloning with proprietary eXcelon technology

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.

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.

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.
