Scintillation Screen Design Options of GAGG(Ce) Scintillators (GAGG:Ce Scintillators)
Freestanding ultra-thin scintillation screen.
Ultra-thin scintillation screens can be coupled to a substrate with optical adhesives in order to achieve better optical readout.
Scintillation screens can be inserted into frames(Aluminum or Stainless steel) for easier manipulation.
We can provide customized marking such as a grid, cross, or scale on the surface of the screen for easier beam visualization.
We can provide various coating on the surface of the screen upon request, such as reflection coatings(Al, Au, Ag, etc.), AR coating, diffusion painting(TiO2, Al2O3), and conductive coatings(Al, ITO, C).
