e2v scientific instruments offers a range of x-ray entrance window choices on all x-ray detector products. The most appropriate selection will depend primarily on application, but factors like window diameter (crystal size) and even operating environment will determine the available options.  

X-ray window
options

The standard generic window types offered by e2v scientific instruments are:

SUTW (Super Ultra Thin Window). The thinnest polymer window available, with excellent low energy transmission. Used almost universally on EDS detectors for electron microscopes (SEM and TEM), but also for any application where light element performance is required. Transmission down to Be-K x-rays.

UTW (Ultra Thin Window). Slightly thicker polymer window than SUTW. Offers good transmission down to C-K x-rays.

DuraBeryllium (TM). A specially coated Beryllium window offering excellent low He leakage rates. These windows are available in 8 and 12µm thicknesses, and offer a relatively rugged solution for applications where transmission above ~1keV is acceptable (Na-K x-ray) or where conditions prohibit the use of polymer windows. Typical applications where DuraBeryllium windows are used are XRF, TXRF and PIXE.

Please contact e2v scientific instruments for more information and to discuss window options for your application.
