Image Intensifiers

Image intensifiers consist of a vacuum tube with photocathode input. This consists of multi-alkali or semiconductor layers. When photons strike the photocathode, electrrons are released via the photoelectric effect. These electrons are then accelerated towards a phosphor screen resulting in the release of light. This light consists of meny photons for each incident photon.

Equipment
OptiSurf® is the ideal tool for non-contact center thickness and air gap measurement within single lenses, planar optics and optical systems. The instrument is based on low coherent interferometry and measures all distances in an optical system with an accuracy of 1 µm in one scan.
The ImageMaster® Universal 3D instrument completes the ImageMaster® Universal family to enable the full field measurement without rotating the sample under test.
PHOTONIS’ Image Intensifiers Tubes are utilized for amplifying low-light level images in a broad range of wavelength to observable levels.
Extensive triggering facilities allow the systems such as the SIL2 to be readily interfaced to most manufacturer’s high-speed cameras, and in particular to high-speed video systems. Constructed around high gain micro-channel-plate image intensifiers, these units provide a wide range of sensitivity, gain and resolution options to satisfy even the most demanding imaging applications.
