PIXIS CCD Cameras for Imaging & Spectroscopy
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. The PIXIS: 256 uses high performance, spectroscopic-format industry standard CCDs, with deep cooling to provide the lowest dark charge. The 1024 array wth 6.7 mm chip height and 26 mm spectral coverage is ideal for multistripe spectroscopy and maximum light collecting area. This detector provides excellent response from the vacuum UV to the NIR, and with its proven system reliability, is ideal for OEM and laboratory applications.
FEATURES
BENEFITS
Permanent vacuum
Our all-metal brazed seals eliminate the outgassing that occurs with epoxy seals and
allows us to offer the industry’s only lifetime vacuum guarantee
Deep thermoelectric cooling
Low temperature operation minimizes dark current without the need for liquid nitrogen
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
Industry standard 1024 pixel imaging array
High performance at low cost
Open electrode architecture
Provides higher QE than standard front-illuminated sensors
Back-illuminated, deep depletion sensor (BR)
Enhanced NIR response relative to conventional back-illuminated detectors, with extremely
low etaloning
Extremely low bin noise
Improves signal-to-noise ratio when binning spectra over multiple rows
Dual-digitizer option
Multiple speed digitization allows complete freedom to select between slow operation for
low noise and highest SNR, or fast operation for rapid spectral acquisition
