We have added a new
Curves section to our catalogue to aide in designing your
filters. We have also added UHV sandwich rings (pictured
above) for applications where no
adhesives or epoxy can be tolerated, to our products.

Lebow foils are a unique product. X-ray filters and windows, ultraviolet
filters and photo cathodes, beam strippers, alpha backscatter substrates, x-ray
laser and particle beam targets are made of the thinnest totally unsupported foils
(0.02-25µS) ever offered as standard products.
Applications of ultrathin metal foils are rapidly expanding in both research and
laboratory instruments. Numerous users routinely depend on Lebow Company for
substantial quantities of our ultrathin foil, so thin its production was, until
now, in itself, a major undertaking.
Our web catalog is an attempt to minimize the difficulty in designing
ultrathin foils into your experiments or instruments. To aid in designing your
ultrathin foils, the best transmission data we have found is available on the
Advanced Synchrotron Light web site at University of California Berkeley:
Our experience in
producing many hundreds of ultrathin foils per year, for over twenty years,
assures our customers worldwide of on time delivery of top quality, as specified,
ultrathin foil. Our ultrathin foils (as large as 10cm diameter) have also been
successfully used in orbital and sounding rocket payloads. Choose a Lebow
ultrathin foil from our web catalogue and concentrate on its successful application.
This web catalogue covers single-layer foils of Aluminum (Al), Aluminum Oxide
Beryllium (Be), Boron (B), Carbon (C), Chromium (Cr), Cobalt (Co), Copper (Cu),
Germanium (Ge), Gold (Au), Hafnium (Hf), Indium (In), Iron (Fe), Kapton®,
Lead (Pb), Lithium Fluoride (LiF), Magnesium (Mg), Magnesium Fluoride (MgF2),
Molybdenum (Mo), Mylar® (PET),
Nickel (Ni), Niobium (Nb), Parylene N® (-C8H8-),
Palladium (Pd), Platinum (Pt), Silicon (Si), Silicon Dioxide (Si02),
Silver (Ag), Tantalum (Ta), Teflon®
Tin (Sn), Titanium (Ti), Titanium Dioxide (TiO2),
Tungsten (W), Vanadium (V), Zinc (Zn), and Zirconium (Zr) up to 25µ
thick (0.001 inch), on most frame sizes and shapes. Backings of mesh or Parylene®
are available but, excepting Mg, Pb, Zn and fluorides, not necessary. In
addition, most materials can be combined as multi-layer ultrathin foils, and
linear arrays of several materials can be built up along slits for multichannel
discrimination. Using a carbon or Parylene-N®
backing, ultrathin foil of metal or compounds can be made in any thickness from
only a few atomic layers up. Please contact us for pricing on these products.
In addition to finished ultrathin foil products (filters, targets and
windows), Lebow Company offers unmounted ultrathin foil from 2.0-25µ
(0.00008-0.001 inch) thick. Unmounted foil of Aluminum (Al), Beryllium (Be), Cadmium (Cd), Cobalt
(Co), Copper (Cu), Gold (Au), Indium (In), Iron (Fe), Kapton®,
Lead (Pb), Magnesium (Mg), Molybdenum (Mo), Mylar®,
Nickel (Ni), Niobium (Nb), Palladium (Pd), Platinum (Pt), Silver (Ag), Tantalum
(Ta), Teflon®, Tin (Sn), Titanium (Ti),
Tungsten (W), Vanadium (V), Zinc (Zn), and Zirconium (Zr) is supplied cut to any
required size up to 100mm x 100mm (4x4 inches). Be foil 5.0-25µ
thick and vacuum tight Be 7.5-25µ thick are
particular specialties. This foil, rolled of
99.8% Be to ±10% thickness tolerances, opens a unique window into experiments
and instruments. Lebow Company also rolls foil to "odd number"
thicknesses up to 1mm (0.04 in.) and cuts foil into any required size or
diameter. We are sorry we supply only small quantities for research and
instruments. We do
not supply coils or roll any alloy foil.
Lebow Company offers unique ultrathin foil metrology capabilities including
an alpha spectrometer, microbalance, foil ultra micrometer and optical
densitometer to support our foil production. We can supply filters and
targets with individually measured light transmission (pinholes), unit weight,
mechanical or alpha particle thickness.
Ultrathin metal foils are usually made to order and are shipped, individually
packed in plastic tubes or boxes, throughout the world, without difficulty.
Ultrathin foil and ultrathin foil assemblies are often inventoried for
"just in time" delivery to meet the needs of instrument makers.. We
maintain an inventory of over 1,000 commonly used foils, stored under dry
nitrogen, often shipping these, mounted on the standard ring of your choice, in
only a few days.
The production of ultrathin metal foils is an evolving art and this only
catches it at a moment in time. Our capabilities are constantly expanding and we
welcome the difficult and the unusual. We are always seeking new and challenging
projects. If any question whatsoever exists in your mind as to the availability
of any foil, even if the material is not in this catalogue, please contact us.
Our thin films work has ranged from coating sub-millimeter
rare earth spots on micro electrodes and fabricating the worlds first micron
diameter multilayer coated wires to designing the metalization system for
coating a six-meter diameter astronomical telescope mirror. In the laboratory of
Lebow Company we use electron beam heated sources to deposit thin films and
foils of the worlds widest range of metals, oxides, sulfides, fluorides,
chlorides, and glasses. We take particular pride in our work with difficult and
toxic materials such as beryllium. We can deposit films in thicknesses ranging
from a few angstroms to several microns on almost anything&glass,
plastic, ceramic, metal, even paper. Our extensive array of special tooling
allows us to meet unusual needs such as coating rods and cylinders, rolls of
plastic or micro-wires. We can evaporate up to six different materials in a
single pumpdown while maintaining the flexibility to economically meet even the
most modest requirement.
About Lebow Company
Over the past 30 years Lebow Company has acquired a wide
range of experience with all types of thin films and deposition equipment. This
experience can be applied in complete confidence and at modest cost to your thin
film problem. Lebow Company does not sell equipment; therefore we can offer
unbiased suggestions and specifications for facilities development and equipment
purchase. Our consulting encompasses laboratory studies, process development,
and thin film tooling design. We offer in-plant consulting to attack complex
problems in thin film production, and personnel training in thin film
Founded in 1973 and located within sight of the Santa Barbara
campus of the University of California, Lebow Company is a research thin film
laboratory specializing in ultrathin metal foil. We have made over 10,000
depositions of films of almost every imaginable material. As the recipient of
two IR-100 awards we have lead in the development of ultrathin metal foil XUV
filters. We offered the first ultrathin beryllium foil and published the world’s
first ultrathin foil catalogue. This technological leadership has continued with
the development of chromium foil, unbacked oxide foils, ROSAT beryllium filters
and, most recently, multilayer micro-wire targets. The staff of Lebow Company
wrote the thin film physics and evaporation sections of The Handbook of Thin
Film Process Technology (Institute of Physics, Bristol, U.K., 1995) and has
published numerous technical papers. As a thank you to the thin film community,
we compile and distribute, without charge, the Lebow Databook, the definitive
source of evaporation technology data.
As a unique thin film laboratory we work with the smallest as
well as the largest users of thin films and foils. We look forward to working
