TRENTON, N.J., Aug. 2, 2011 — Princeton Instruments' PyLoN series 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 that use 1340 × 100 and 1340 × 400 sensors, respectively.
In creating the new platform, the company redesigned its Spec-10 family of cameras to remove the external controller, 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.
Both cameras provide dual amplifiers and software-selectable gain that permits operation in high-sensitivity mode for Raman or single-molecule spectroscopy, and in high-capacity mode for fluorescence spectroscopy. The 2-mm array height of the PyLoN:100 facilitates rapid spectral acquisition, and the 8-mm array height of the PyLoN:400 is suitable for multiplexed spectroscopy.
The CCDs feature 20 × 20-µm pixels, offering researchers a combination of high resolution and a wide dynamic range. The cameras deliver analog-to-digital conversion rates of up to 4 MHz, with digital bias stabilization and correlated double sampling for decreased read noise and improved linearity. Kinetics mode allows microsecond-resolved kinetic spectral acquisition, and custom sensor mode increases control over the camera readout, enabling spectral rates of >1000 fps.
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 patent-pending IntelliCal wavelength and intensity calibration packages. The Gigabit Ethernet interface enables remote operation via a single cable without the need for custom frame grabbers. The cameras are available with or without a 40-mm shutter.
