TRENTON, N.J., Nov. 23, 2012 — Princeton Instruments has launched the PyLoN-IR, controllerless, cryogenically cooled CCD cameras for spectroscopy.

The linear InGaAs photodiode array cameras are designed for quantitative near-infrared and short-wavelength-infrared applications that demand high sensitivity, including photoluminescence and Raman spectroscopy.

Liquid nitrogen cooling reduces the dark current that occurs from thermal energy within the CCD, and indium metal seals enhance vacuum longevity. The InGaAs detector offers 16-bit digitization, a rate of up to 6600 spectra per second and low system read noise. The cameras offer ultralow-noise electronics.

Two PyLoN-IR models are available. Model 1024-1.7 is responsive in the UV and visible with sensitivity from 800 nm to 1.7 μm, and the 1024-2.2 version’s spectral range is from 1 to 2.2 μm.

The cameras run on 32- and 64-bit Microsoft Windows operating systems and are fully supported by proprietary LightField 64-bit data acquisition software featuring the patented IntelliCal spectrograph calibration system. The latest Gigabit Ethernet interface allows remote camera operation via a single cable without the need for custom frame grabbers. The cameras are available with or without a 40-mm shutter.

GLOSSARY
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.
