Charge Dissipation and Light Rejection
Moxtek proportional counter windows are composed of an ultra-thin layer of Moxtek polymer, a resistive DuraCoat®, a charge dissipative aluminum coating, and a strong support structure composed of silicon.
Moxtek proportional counter windows are supported by a rigid silicon grid. This patented window design enables the window to withstand over 1.2 atmosphere of differential pressure. This window can withstand over 100,000 cycles at that same differential pressure without degradation in window performance. Pressure Limits: 1.2 atm frontal pressure, 0.3 atm backside pressure.
Moxtek proportional counter windows are capable of exposure to 85° C at a differential pressure of 1 atm.
Moxtek proportional counter windows are coated with aluminum for charge dissipation and light rejection. A custom thickness can be requested.
