ns-Resolved Intensified Camera
Princeton Instruments intensified CCD Camera PI-MAX3 is unique device cappable of recording fast and/or low-light processes. It will find its applications in low-light signals studies (typical application of iCCD cameras is in the field of night-vision). I.e. in physics it will be e.g. spectroscopy, in astrophysics e.g. low-light fast events or in chemistry e.g. fluorescence. It will find its aplication in fast processes study to the greater extent. iCCD cameras enables study of physical systems such as plasma kinetics, LIF, PIV or the reaction kinetics in chemistry or LIL in nanotechnology research. This all with superb spatial resolution of 1 MP and in broad spectral range of 200 – 900 nm.
Next unique feature of this camera is its dual-image capture capability, i.e. it enables one to capture two consecutive full frame images in succession of 2 us or more. Due to this it can be used for non-periodic system dynamics – real time recording.
High repetition rate of intensifier (1 MHz) gives the ability of fast data acquisition with much better SNR – common iCCD cameras are 1-2 orders worse. High frame rate (26 fps) gives the possibility of motion-capture even in very low light conditions.
