ProEM The ProEM camera
from Princeton Instruments
is the most advanced
EMCCD camera available
on the market today,
utilizing the latest
low-noise read out
electronics and
a 512x512 back illuminated
EMCCD to deliver
single photon sensitivity.
This true 2-in-1
camera features
a high speed EM
mode to capture
fast kinetics and
a low speed normal
CCD mode with very
low read noise for
precision photometry
applications. It
provides advanced
features such as
solid baseline stability
and linear EM gain
control. The ProEM:
512B is cooled to
below -90°C using
either air or liquid,
or a combination
of both. The ProEM
EMCCD camera
also features, for
the frst time, the
latest Gigabit Ethernet
(GigE) interface
that allows remote
operation over a
single cable without
the need for custom
framegrabbers.

Cooling ProEM uses the most advanced vacuum and cooling
technology with all-metal hermetic seals
to achieving deep cooling and consequently low dark noise.Even the
vacuum window -the only optical surface in the optical path, is brazed (fused at
molecular level) to the vacuum chamber.

Low Noise PINS (Princeton Instruments Noise
Suppression technology): Princeton Instruments' engineers have used the next
generation electronics to get the lowest possible noise levels in ProEM. In EM
mode, the ProEM delivers the lowest starting read noise of any camera in the
market –an advantage considering only a small amount of EM gain is required to
achieve <1 e- rms effective read noise.For traditional readout port, the camera delivers 3 e- rms read noise at
100kHz, an unparalleled performance. Now, whether it is fast or slow
application, the ProEM delivers the lowest noise combination ever to be
achieved.Part of the technology also includes proprietary methods to reduce
clock induced charge –an unwanted noise source in EM applications requiring
single photon detection. It is reduced to 0.005 e-/p/frame with careful
optimization of clock timing and voltage levels on every
camera. At the heart of ProEM is a back-illuminated EMCCD that delivers
greater than 90% quantum efficiency and less than 1 e- rms read noise when
electrons generated in each pixel (from the incident photons) via impact
ionization.

Precision OptiCAL: EM calibration gone optical! A precision light
source built into every camera is used to generate a linearized EM gain map on
demand by the user. In the software, you are controlling the EM gain in absolute
steps.IAnti-ageing: IEM gain can degrade over time
especially when a large gain is used in high light conditions. ProEM uses every
anti-ageing measure including clock voltage optimization to reduce the effect of
ageing. The deep cooling allows the high voltage clocks to be operated well
below the maximum ratings, while still achieving greater than 1000x EM gain.

Traditional CCD or “Non-EM” mode: While the
EM mode is ideal for low light, high speed imaging applications, the non-EM or
traditional readout amplifier is the best for slow scan applications - for
example, astronomical imaging requiring minutes to hours of exposures. By
reading out slowly, ProEM delivers 3 e- rms read noise at 100kHz even in non-EM
mode.
Options Numerous options - No more
compromises! ProEM delivers the highest performance using air, liquid or a
combination thereof. The cameras can be cooled below -95C for the lowest dark
noise. For traditional readout port, the camera delivers 2.5 to 3 e- rms read
noise at 100kHz, an unparalleled performance. Now, whether it is fast or slow
application, the ProEM delivers the lowest noise combination ever
achieved.
Speed Video frame rates and
up: ProEM provides better than video rate even at full resolution
(512x512). But if you need hundreds of frames per second, a combination of
binning and region of interest (ROI) can be used. For even higher frame rate, a
“custom chip” mode allows 3 to 4 times higher frame rate when only a partial
area of the CCD is illuminated.
Kinetics: Need to capture a process with microsecond
time resolution or at millions of frames per second in a burst? ProEM fully
supports Kinetics -a special readout mode - right out of the box. By
illuminating only a small portion of the sensor, a series of sub-frames can be
captured and shifted in microseconds vastly increasing the time resolution.
