Both sides aluminum metallized polyester film is an extremely thin polyester film ,the thickness of aluminized layer usual is 1000 angstroms per side. Of course , we accept custom aluminized layer thickness from 600angstroms to 3000angstroms . 2micron both sides aluminum metallized PET film specifically fabricated for use in alpha and beta particle radiation detectors as a light-tight radiation window.
Both sides Aluminized polyester film is a kind of reasonably priced materias that will allow the passage of alpha particles while blocking all light.so the aluminized polyester material is often referred to as alpha film, It can be also used as a very thin opaque window for low energy gamma, x-ray, and xrf detectors.

The Aluminized polyester film is usually used in two layers that will be assure light tightness. Two layers makes it less likely that any two pinholes or defects line up to allow passage of light into the scintillator.

2 layers will stop approximately 1 mev of energy from an alpha particle |
