Breadboards and Optical Table Tops
All LINOS Optical Table Tops are of
unique design. Our consistent use of all
theoretical principles resulting in
superior stiffness and optimized internal
damping has led to their being ranked
among the best Optical Table Tops
commercially available. Major features
include:
••
Small cell, steel-honeycomb cores
••
Steel top/bottom plates and sidewalls
••
Threaded holes tapped directly into their
top plates
••
Patented „CleanTop II“ sealing of all
tapped holes
••
Hybrid, integral, damping mechanisms
••
High-strength, non-aging, epoxied joints
••
Broad range of standard models•

Design Features
All of our Optical Tables are laminated
structures con sisting of steel top and
bottom plates bonded under high
pressure, by two lapped granite plates,
to steel-honey comb cores using a special
epoxy resin. Their sidewalls are fabricated
from steel plates, and seam-welded
to other structural elements to form rigid
structural units. All Table Tops are
equipped with specially tuned, inter nally
mounted, damping mechanisms, such as
damping mats laminated onto the inner
surfaces of their sidewalls and damping
masses installed at strategically chosen
internal points. Their broadband
characteristics make them equally
effective at all frequencies.
Our „Clean-Top®“ option seals the
bottoms of tapped holes in Table Tops
with special tubular caps that prevent
liquids that might attack bonding
adhesives from entering the interiors of
Table Tops.
Steel-honeycomb Cores
Our steel-honeycomb cores are fabricated
from 0.25 mm gauge corrosion-resistant
coated sheet steel. The small
diameters of the tubular caps used on
Table Tops equipped with our Clean-Top
option have allowed us to reduce
honeycomb-cell cross-sectional area to 3
cm 2 . The resulting high cell density yields
extremely stiff table-top structures. This
high cell density also provides large
contact areas for bonding top and
bottom plates to honeycomb cores,
making Table Tops even stiffer. Our
honeycomb cores incorporate even
smaller cell cross-sections at strategic
points, which increases their ave rage mass
density to 0.27 g/cm 3 . This type of
honey comb -core design has a shear
modulus of 1.9 x 10 9 N/m 2 .
Top Plates
Top plates are fabricated from coldrolled
ferromagnetic stainless steel, and
directly bonded to honeycomb cores by a
bonding process that leaves them

unstressed. Top plates are available in
thicknesses of 3 mm or 5 mm, and are
flat to within ±0.13 mm over the entire
surface. The upper surfaces are ground
to reduce disturbing reflections.
Bottom Plates
Bottom plates are bonded to honeycomb
cores using the same process used for
bonding top plates, and are also left
unstressed. Bottom plates are fabricated
from cold-rolled steel and coated with
black epoxy paint. The unique, direct
core-to-top bonding improves the
thermal conductivity of the core to the
outside environment, reducing the
„thermal relaxation time“ for the top.
Bot tom plates have the same thickness as
top plates.
