Luxel filters can withstand Torr level pressure differentials for gas and vacuum separation applications.
Filter foils can be composed of standard or custom foil materials. Filters may be mounted in VF111 frames to fit in the VAT gate valve (shown) or mounted in custom frames to your specifications.
The Luxel VF111 filter line brings several advantages to the soft X-ray researcher. The filters thread into a VAT gate valve and are designed to reject visible light, to remove soft scattered radiation, and to discriminate within the X-ray/EUV bandpass area of interest.
UHV compatible: will separate UHV from normal vacuum experiments
Field interchangeable: minimize interruption of active experiments
16 mm clear aperture
Support Torr-level pressure differential
Gas cells / monochromator calibration
Synchrotron beamline research
Gas proportional counters
The VAT P/N 01032-CE01-X window valves are compact, yet they hold a relatively large window mounted in the gate. The valve is only 35 mm flange-to-flange and employs only one moving part in the vacuum. It provides nearly particle free and shock free operation, and accepts Luxel VF111 filters in the threaded window recess.
Filter Mounting and Construction
Luxel uses techniques we developed for spacecraft missions in fabricating all our filters. The filter material is vacuum deposited. Usually, support mesh is applied to the foil, and the filter material is bonded to the window frame. Lexan® and polyimide can be supplied free-standing, if desired. All materials are UHV compatible.
