Generally speaking phosphor screens are used for the visualisation of particles or energetic photons. The most typical applications are in the fields of electron microscopy, X-ray imaging, synchrotron radiation, neutron & ion imaging. The phosphor coating is prepared by sedimentation of phosphor grains on a substrate (plain glass, quartz, fibre optic block or taper, CCD chip, prism, metal)
Scintillating Screens主要參數:
-
P43, P46, P47, P11 and other scintillators
-
ITO, chromium, aluminium, water glass coating
-
segmentation of the coating area possible
-
5 mm – 250 mm diagonal, bigger on request
-
on any plain and rigid surface (metal, glass, plastic)
-
coating of special forms like prisms, tapers and others possible
-
coating of all line and area CCD/CMOS elements without protection window (Removing of the window is provided as a service)
-
coating thickness up to 50 µm
Scintillating Screens 特點:
Our sedimentation process leads to a very homogeneous layer structure. To guarantee a homogeneous layer structure, at least 3 to 4 layers of phosphor grains are necessary. The minimum average grain size available is 1 µm. The maximum thickness of the phosphor coating is up to ca. 50µm.
The resolution limit RL is defined as the spatial frequency resulting in a modulation transfer function MTF with a value of 3%. RL is measured in linepairs/mm (lp/mm) and can be approximated as RL = 500/D. Up to 100lp/mm are possible.
The screens are stable under vacuum conditions and can resist temperatures up to 400°C.
The Substrates can be provided by customer or ProxiVision can manage the procurement service of special customized substrates.
