PIXIS: 2K
2048 x 512
The PIXIS series from Princeton Instruments (PI) are fully integrated, low noise cameras designed for quantitative scientific imaging
optical spectroscopy applications. Designed utilizing PI’s exclusive XP cooling technology, PIXIS offer thermoelectric cooling down to
-75°C, while the all-metal, hermetically sealed design, with the industry’s only lifetime vacuum guarantee, ensures maintenance free
operation. Choose either back-illuminated (B/BUV) or eXcelon versions of the 2048 x 512 CCD, for optimized performance from
UV to NIR. High QE and ultra low-noise electronics make the PIXIS: 2K series of cameras ideal for demanding, low light applications
such as Raman spectroscopy, LIBS, absorbance, emission, fluorescence and reflectance spectroscopy. Princeton Instruments’ eXcelon
technology delivers the highest sensitivity in the NIR while suppressing the etaloning that occurs in standard back illuminated CCDs.
Dual speed operation at 100kHz or 2MHz allow these cameras to be used for steady state as well as fast kinetics studies.
FEATURE
BENEFITS
eXcelon® technology
Increases detector sensitivity while suppressing etalon interference fringes observed in the
NIR with conventional back-illuminated devices.
Permanent vacuum
Our all-metal brazed seals eliminate the outgassing that occurs with epoxy seals and allow
us to offer the industry’s only lifetime vacuum guarantee.
Deep thermoelectric cooling
Low dark noise allows detection of faint signals; CoolCUBE II, a compact room temperature
coolant circulator, is available for vibration sensitive environments.
Single fused silica vacuum window
Minimizes reflection losses from the UV to the NIR;
Optional AR coating and wedge windows are available.
Optional UV phosphor coating
Enhances sensitivity throughout the UV to below 200 nm.
2048 x 512 imaging array,
13.5mm x 13.5mm pixels
CCD format provides 6.9 mm height for rapid spectral acquisition; 13.5 mm pixel size
offers superior resolution to industry-standard detectors with a 1024 pixel format.
100 kHz and 2 MHz digitization rates
Dual-speed digitization allows complete freedom to select between slow operation for low
noise and highest SNR or fast operation for rapid image acquisition.
Dual amplifiers with software-selectable system gains
High sensitivity amplifier reduces noise for weak signals;
High capacity amplifier increases dynamic range.
USB2.0 data interface
Plug-and-play operation with desktops or laptops;
Optional fiber optic interface for remote operation; Easy OEM integration.
Optional: LightField® (for Windows 8/7, 64-bit)
Or WinView/Spec (for Windows 8/7/XP, 32-bit)
Flexible software packages for data acquisition, display and analysis;
LightField offers intuitive, cutting edge user interface, IntelliCal® and more.
PICAM (64-bit) / PVCAM (32-bit)
software development kits (SDKs)
Compatible with Windows 8/7/XP, and Linux;
Universal programming interfaces for easy custom programming.
