Image Intensified Cameras

X-ray Image Intensified Cameras

X-ray image intensifiers are devices which detect an X-ray image and convert it into an image of visible light, which is then transferred through a set of lenses to a video camera and displayed on a monitor. These parts are mounted in a high vacuum environment within glass or, more recently, in a metal/ceramic structure.

Image intensifiers are also the ideal choice for non-destructive inspection of low density materials in the low-energy X-ray region, and for radiation imaging.Image intensifiers which utilize a beryllium input window instead of the more normal aluminium (Al), drastically improves X-ray transmittance in the low-energy X-ray region for improved imaging, as shown in fig 1. The internal structure of materials such as thin plastic and aluminium can now be seen in real-time with a high contrast, which up until now was impossible.

The latest development in imaging technology, scientific CMOS (SCMOS) sensors simultaneously deliver high sensitivity, fast readout speeds, and low noise without the addition of multiplicative noise associated with EM-CCDs.
