  • PI-MAX3-MG ICCD Cameras
Dec 2010
Princeton InstrumentsRequest Info
TRENTON, N.J., Dec. 16, 2010 — For UV-blue gated imaging applications, Princeton Instruments has announced the addition of the PI-MAX3-MG models to its line of intensified CCD (ICCD) cameras. They feature microchannel plate gating technology to provide a combination of high sensitivity and fast gating speed and are especially suited to UV-blue applications such as planar laser-induced fluorescence imaging in combustion research.

Typically ICCD cameras can achieve <5-ns gating speed using intensifiers based on multi-alkali photocathodes. To achieve fast gate speeds, additional metal under-layers may have to be added, reducing quantum efficiency. Slow gate tubes, without the use of metal under-layers, have high sensitivity but can gate down to only 200 ns. The PI-MAX3 MG models combine the quantum efficiency of slow gate tubes and a gating speed of <8 ns. They are suitable for time-resolved UV-blue applications using pulsed lasers where high sensitivity and fast gating are important.

The cameras feature a built-in SuperSynchro timing generator that makes setting up complex time-resolved imaging experiments easy. Researchers can use SuperSynchro to store a sequence of gate delays and widths and execute them quickly to generate time vs. intensity data with just a few clicks of a mouse. SuperSynchro also provides low insertion delay.

Another feature, SyncMaster technology, helps reduce lab clutter by eliminating the need for an external timing generator. SyncMaster allows the camera to output two continuously running pulse trains to trigger pulsed lasers without interruption, or to trigger Q-switched flashlamp lasers or double-pulse lasers separately. Because the cameras’ programmable gate widths and delays are generated from the same master clock, the resultant jitter is the lowest possible, typically determined by the laser jitter.

The latest Gigabit Ethernet interface allows the cameras to be operated from distances greater than 50 m away, important for applications such as combustion or plasma studies in which the camera must be kept at a safe distance from host computers.

PI-MAX3-MG models are available in 1024 × 1024 (1024i) and 1024 × 256 formats. All use a windowless design for maximum light throughput, and they feature photocathode cooling for ultralow-light or single-photon imaging as well as special readout modes for single-shot measurements and particle imaging velocimetry applications.
