Introduction
PIXIS
Thank you for purchasing a PIXIS camera system
from Princeton Instruments. For over two decades
Princeton Instruments has been the legendary name
behind the most revolutionary spectroscopy and
imaging products for cutting edge research.
PIXIS represents the most advanced camera design and utilizes years
of experience and expertise in low-light detection. Whether your
application involves Raman spectroscopy in the near infrared or
semiconductor imaging in the ultraviolet, PIXIS has everything you need to tackle the
most demanding applications.
Among the many state of the art features are its maintenance-free permanent vacuum,
integrated controller, deep thermoelectric air-cooling, and compact design. Currently the
platform supports several imaging and spectroscopy CCDs, including eXcelon
®
enabled
back-illuminated spectroscopy CCDs. Please visit www.princetoninstruments.com for the
current list of supported CCDs.
eXcelon
®
eXcelon is a new CCD/EMCCD sensor technology jointly developed by Princeton
Instruments, e2v, and Photometrics. Spectroscopy CCDs using this technology provide
three significant benefits:
Improved sensitivity – improved QE over broader wavelength region compared
to back-illuminated sensors,
Reduced etaloning – up to 10 times lower etaloning or unwanted fringes in near
infrared (NIR) region compared to standard back-illuminated CCDs,
Lower dark current – similar to back-illuminated CCDs or 100 times lower
than the deep depletion CCDs.
Advanced Design
PIXIS is a fully integrated camera system. The camera contains all of the electronics
necessary to read out and control the CCD device. For instance, it houses precision analog-
to-digital converters (ADCs) positioned close to the CCD for lowest noise and has USB 2.0
electronics to interface with the host computer.
The easy-to-use PIXIS camera system offers all basic CCD camera functions such as
region-of-interest (ROI) selection and binning --- all under software control. It also
provides advanced triggered operation as well as programmable TTL output.
