Luxel is the preeminient supplier of submicron
foils for the soft X-ray and EUV portions of the electromagnetic spectrum. Luxel's
filters have been utilized in the majority of soft X-ray and EUV space
astronomy missions flown since the early 1970's.

Custom Sizes and Specifications on Request
For filters to perform in the soft X-ray and EUV spectrum, the
foils fabricated must be ultra-thin. Filter foils are most often a few hundred
angstroms reaching occasionally up to several microns in thickness. Bandpass
characteristics and mechanical properties are the two most important factors in
determining filter materials. Aluminum is the
most commonly used material because it has a wide X-ray bandpass, eliminates visible
light, and has excellent mechanical properties.
All filters are extremely fragile, and normally the foils are
provided with a fine mesh support. Mesh supported metallic foil filters
are typically constructed of electroformed nickel that is 70 lines per inch, which typically transmits
about 82%. Other supports are available, most commonly, thin film polyimide.

maximum visible transmittance is available for our standard product line. For current production filter transmission data, click here...

Luxel manufactures three standard frame styles (including mounting
in a VAT valve) that are available in several sizes. We will also supply custom
filters and windows mounted on your frames.
We pride ourselves on the custom design, development and
fabrication of custom filters for your research applications.

Note: Certain filter material types are simply too fragile to exist
without support provided by using 70 line-per-inch
electroformed nickel mesh.
