TRING, England, Feb. 14, 2011 — Specialised Imaging has recently supplied its SIM-D ultrafast framing camera in a new multispectral imaging configuration.

It can fit up to 16 filters with wavelengths from 400 to 850 nm within the optical system. The camera takes images at exposure times down to 3 ns with zero interframe time, enabling applications such as colorimetry, temperature measurement, and studying wavelength dispersion when materials are stressed. It operates at up to 1 billion fps.

The optical design offers the choice of up to 16 separate optical channels without compromising performance or image quality. Effects such as parallax and shading are eliminated, and the high spatial resolution of >36 line pairs per millimeter is the same from frame to frame and in both axes. Individual ultrahigh-resolution intensified CCD detectors controlled by state-of-the-art electronics offer almost infinite control over gain and exposure, allowing researchers to capture images of difficult transient phenomena.

An optical periscope for focus adjustment enables rapid and simple experimental setup and optimization. Comprehensive triggering facilities, accurate timing control and a wide range of output signals, coupled with a software package that includes full measurement and image enhancement functions, simplify image capture. Full remote operation using Ethernet connectivity is supplied as standard, facilitating integration into almost any environment.

Applications include automotive testing, biomedical research, combustion research, failure dynamics, impact studies, nanotechnology and university research.
