ProLINE™ Series Polymer X-ray Windows

ProLINE Series X-ray windows are available in typical sizes used in wavelength dispersive spectrometers such as those from major wavelength dispersive equipment manufacturers.

ProLine X-ray Window

ProLINE Series x-ray windows provide an excellent transmission in the low energy range of F-Kα and down to B-Kα. ProLINE Series windows are the thinnest WDXRF windows manufactured by Moxtek® and these windows outperform stretched polypropylene and other commonly used windows.

ProLINE Series 10 Ultra-thin windows do not have a metal support grid. These windows have withstood hundreds of cycles at a differential pressure of 1.2 atmospheres without degradation in window performance.

ProLINE Series 20 windows are supported by a strong metal support grid and have withstood hundreds of cycles at a differential pressure of 1.2 atmospheres without degradation in window performance.

ProLINE Series X-ray windows typically have a leak rate of less than 1 x 10-3 mbar L/sec He. Most ProLINE Series 10 windows are coated with 200 angstroms of aluminum for charge dissipation.
Window active area geometry can be circular or rectangular. Maximum rectangular active area dimensions are 2.8” x 2.8” (70 x 70 mm). Maximum active area diameter is 4.0” (10.16 mm). The following table shows the standard film thicknesses available at Moxtek. Other thicknesses can be custom manufactured.
