DIF (Double Image Feature):
The PI-MAX4:1024i uses an interline CCD to enable capture of two full-resolution images in quick succession. It quickly transfers a full-resolution image under the interline CCD pixel’s adjacent mask area, enabling the camera to take a second frame in as little as 450 ns (limit imposed by P46 phosphor decay time). The ability to apply the intensifier gate within two frames means lower background even when used with CW laser sources.
Picosecond Gating Technology
PI-MAX4: 512EM(B), PI-MAX4:1024i and PI-MAX4:1024x256 cameras utilize new Princeton Instruments Picosecond gating technology to achieve <500 psec gating, thus delivering exceptionally high temporal resolution for effective background discrimination. And best of all, we achieve this without sacrificing standard intensifiers quantum efficiency!
Ultimate in Intelligence
LightField Software
Princeton Instruments LightField is a new 64-bit data acquisition software platform that has been designed “from the ground up” for scientific imaging and spectroscopy. LightField provides comprehensive control of the PI-MAX4 via easy-to-use tools that help streamline experimental setup, data acquisition, and post processing. LightField is an excellent solution for multi-user facilities.
SuperSynchro Timing Generator
This new precision timing generator built right into the camera head controls intensifier gating, allowing gate widths and delays to be set in 10 psec steps with less than 35 psec rms jitter. It offers a wide variety of options to synchronize the camera with external trigger sources (e.g., pulsed lasers). Now, users can easily set up time-resolved experiments, even ones with complex timing requirements.
SyncMaster:
The PI-MAX4 features a SyncMaster signal output based on the camera’s high-precision internal clock. This signal can be used to continuously trigger pulsed-laser sources. Since the intensifier gating is based on the same clock, the jitter in the whole experiment is kept as low as possible (often only limited by the laser jitter)! In addition, by eliminating the need for external delay generator boxes, valuable lab space is conserved.

Princeton Instruments Noise Suppression Technology
Princeton Instruments’ next-generation electronics ensure the best combination of CCD readout speed and lowest possible noise levels in a scientific ICCD camera.
Mounting
Intelligent mount design allows changing C-mount, F-mount and spectroscopy mount quickly and easily in the lab and still stay in focus. Our factory calibrated mounts are designed for precision camera focusing no matter what the application. Furthermore, the flexible optical mount design makes it easy to mount the camera on an English or Metric standard optical table.
Photocathode Cooling
EBI (equivalent background intensity) refers to the thermal emission from photocathode of the intensifier. The PI-MAX4 camera has a provision to cool the photocathode to reduce EBI by as much as 20 times. This is an important consideration for ultra-low light and single photon level measurements.
Gigabit Ethernet (GigE):
This high-bandwidth (125 MB/sec or 1000 Mbps) data interface affords real-time image transmission. The interface supports remote operation from more than 50 meters away.
PI-MAX4 RF for frequency domain imaging applications
RF Modulation
The PI-MAX4:1024i-RF camera enables frequency domain measurements for fluorescence lifetime studies, in addition to time resolved imaging, with minimal external equipment. By modulating the gain of the Gen III filmless intensifier at a radio frequency (RF) rate, the camera operates as a 2D lock-in amplifier. Each pixel acts as an individual phase-sensitive (lock-in) detector. The PI-MAX4:1024i-RF can be utilized for advanced imaging techniques such as FLIM and FRET.
