ProEM+ Camera
CCD Array: The ProEM+ camera systems are the most advanced EMCCD cameras
available on the market today, utilizing the latest low-noise read out electronics and back-
illuminated EMCCDs to deliver single photon sensitivity. In addition, these cameras
feature, for the first time, the latest Gigabit Ethernet (GigE) interface that allows remote
operation over a single cable without the need for custom frame grabbers. The all metal,
hermetic vacuum seals used in the ProEM+ cameras are warrantied for life - the only
such guarantee in the industry. In addition to the standard version of these EMCCDs,
eXcelon versions offer the lowest etaloning in the NIR, and enhanced QE in blue and red.
The ProEM+:512B 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 -80°C using either air or liquid, or a combination of both.
The ProEM+:512BK features a high speed EM mode to capture fast kinetics, a low speed
normal CCD mode with very low read noise for precision photometry applications, and
advanced features such as solid baseline stability and linear EM gain control. These
cameras are cooled to below -90° C using either air or liquid, or a combination of both,
while the all metal, hermetic vacuum seals are warrantied for life – the only such
guarantee in the industry – and feature the latest Gigabit Ethernet (GigE) interface to
allow remote operation over a single cable without the need for custom framegrabbers
The ProEM+:1024B provides a large field of view with 13.3 x 13.3-mm imaging area,
and 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+: 1024B is cooled to below -65°C using either air or liquid, or a combination of
both.
The ProEM+:1600
(2)
and ProEM+:1600
(4)
feature back-illuminated full frame
spectroscopy EMCCDs with the benefit of eXcelon technology. The ProEM+:1600
cameras are cooled to below -65°C using either air or liquid, or a combination of both.
These cameras incorporate an internal manual shutter and have 3.60” and 3.88” bolt
circles for mounting Acton Series spectrographs. The flange-mount (3.60” bolt circle)
version of these cameras can be mounted to Acton Series or IsoPlane spectrographs.
Cooling: Dark current is reduced in ProEM+ camera systems through thermoelectric
cooling of the CCD arrays. Cooling by this method uses a Peltier cooler in combination
with air-circulation (i.e., fan) and/or circulating coolant. To prevent condensation and
contamination from occurring, cameras cooled this way are evacuated. Due to CCD
size/packaging differences, the lowest achievable temperature can vary from one
ProEM+ model to the next. Please refer to the specific system’s data sheet for cooling
performance.
A feature of air-cooled ProEM+ cameras is software control of the fan On/Off status. When
vibration may affect results, the user can turn off the fan operation while making sure that the
coolant is circulating through the camera to maintain the CCD cooling temperature.
The camera needs to have at least two (2) inches (50 mm) clearance around the vented
covers. The operating environment of the camera can be from 0 to 30°C with a 0 to 80%
relative humidity (non-condensing). For better performance the ambient temperature
