Princeton Instruments has introduced the PyLoN-IR, controllerless, cryogenically-cooled CCD camera for spectroscopy. The device is a linear InGaAs photodiode array camera and is designed for quantitative near-infrared and short-wavelength infrared applications that demand the high sensitivity, including photoluminescence and Raman spectroscopy. PyLoN-IR replaces PI’s OMA V InGaAs detector linear photodiode array camera.

The camera’s liquid nitrogen cooling greatly reduces dark current that occurs from thermal energy within the CCD, and its indium metal seals enhance vacuum longevity. The InGaAs detector offers 16-bit digitisation and has a spectral rate of up to 6,600 spectra/sec.

Two PyLoN-IR models are available with wide spectral coverage. Model 1024-1.7 is responsive in UV and visible with high sensitivity from 800nm to 1.7μm, with the 1024-2.2 version’s spectral range from 1.0-2.2μm.

PyLoN cameras operate on 32-bit and 64-bit Microsoft Windows operating systems and are fully supported by LightField, Princeton Instruments’ advanced, 64-bit data acquisition software featuring IntelliCal spectrograph calibration system. The latest Gigabit Ethernet (GigE) interface allows remote camera operation via a single cable without the need for custom frame grabbers. The cameras are available with or without a 40mm shutter.
