M.E.L.B.A. Multi Element Bolometer Array
Bolometer-Arrays with highest resolution are the key-diagnostic in
nuclear Plasma-reactors of tomorrow.
Controlled nuclear fusion requires miniaturized, low-noise
metal-layer bolometer-arrays for the broad band measurements of
radiation emmited by the plasma.
M.E.L.B.A.-Technology offers the most advanced versions of
metal-layer bolometer-arrays. Unmatched sensitivity with
unprecedented signal to noise ratio, perfect in situ calibration and
unparalleled long term stabilility with a range of operation up to
400°C and marginal temperature drift.
M.E.L.B.A.-Technology is black in a wide spectral range from IR- to Soft-X-field.
M.E.L.B.A.-Technology is robust against high magnetical fields, ultra high
vacuum and intensive nuclear radiation.
M.E.L.B.A.-Technology provides integrated Wheatstone-bridge with
remarkable symetry. A prerequisite for optimal suppression of
electromagnetical, thermal and nuclear interfering signals.
M.E.L.B.A.-Technology is the result of modern fabrication processes
combined with a radical redesign of the bolometer layout.
M.E.L.B.A.-Technology means Bolometer-Arrays with smallest footprint.
M.E.L.B.A.-Technology allows fine tuning thermal properties exactly to
M.E.L.B.A.-Technology is a consistent enhancement of the well-known
metal-layer-bolometers already in use in plasma-reactors for over 20
M.E.L.B.A.-Technology is faster, more robust, more sensitive, smaller
and more versatile, than any other hitherto known bolometer-type.
M.E.L.B.A.-Technology offers miniaturized bolometer-cameras with up to
30 integrated channels on one foil with almost no property variations from channel to channel.
M.E.L.B.A.-Technology has and will be constanly improved
for a wide range of applications hitherto unimaginable for
M.E.L.B.A.-Technology is carried by their
inventors (K.F.Mast and P.Betzler).
Our goal is to provide best performance bolometers based on 20 years
