Princeton Instruments’ controllerless, cryogenically cooled CCD cameras are designed for quantitative spectroscopy applications that demand high sensitivity. The first commercially available models are the PyLoN:100 and PyLoN:400 dual-amplifier cameras, which use 1340 x 100 and 1340 x 400 sensors, respectively. In creating the new platform, the company redesigned its Spec-10 family of cameras to remove the external controller, thus increasing experimental flexibility and improving the ultralow-noise electronics. Liquid nitrogen cooling virtually eliminates dark current, and indium metal seals enhance vacuum longevity. Binning noise has been reduced. The amplifiers and software-selectable gain permit operation in high-sensitivity mode for Raman or single-molecule spectroscopy, and in high-capacity mode for fluorescence spectroscopy. The PyLoN:100 is suitable for rapid spectral acquisition and the PyLoN:400, for multiplexed spectroscopy.

correlated double sampling
A technique for removing thermal noise and drift from focal plane assemblies by sampling the system output between views of scene elements and then subtracting the resulting value from the subsequent reading.
fluorescence spectroscopy
The spectroscopic study of radiation emitted by the process of fluorescence.
Raman spectroscopy
That branch of spectroscopy concerned with Raman spectra and used to provide a means of studying pure rotational, pure vibrational and rotation-vibration energy changes in the ground level of molecules. Raman spectroscopy is dependent on the collision of incident light quanta with the molecule, inducing the molecule to undergo the change.
