AP3 Ultra-thin Polymer X-ray Windows AP3 Ultra-thin Polymer X-ray Windows are the highest performing x-ray windows available for low energy x-ray analysis. AP3 windows are ideal for applications that require high x-ray transmission of light element energies, high mechanical strength, light rejection, vacuum tightness, and reliability. AP3 Windows are composed of ultra-thin layers of Moxtek polymer, DuraCoat®, and aluminum. The proprietary Moxtek DuraCoat treatment enables the AP3 window to withstand hostile environments. DuraCoat provides exceptional corrosion resistance in 100% humidity.
AP3 Windows are supported by a rigid silicon grid with 77% open area. This patented window design enables the window to withstand over 1.3 atmospheres of differential pressure. AP3 Windows have survived over 100,000 cycles at a differential pressure of 1.2 atm without degradation in window performance. AP3.3 Windows are used in applications that require the highest transmission of low energy x-rays. AP3.7 Windows are used in applications where maximum light element sensitivity is not required. Both of these windows are used in applications where conventional beryllium windows are ineffective. MountingThe window must be mounted with the front side (the reflective side) facing the high-pressure side of the instrument. Never allow the window to experience more than 2 atm of differential pressure in the forward direction or 1 atm in the reverse direction (back pressure). Customer supplies mount or mount design. |
