As an option on 2 in. (50 mm) thick breadboards
with 1/8 in. (3 mm) or 3/16 in. (5 mm) skins, TMC provides a breadboard
leveler mechanism. The leveler consists
of a threaded sleeve bonded into the top, a bushing leveler, and
a locknut. An M6 or 1/4-20 bolt may then be used to fasten the breadboard
to another top. The leveler is adjusted and locked with a simple
How to Order
Specify the number of levelers required at the
end of the breadboard model number suffix. For instance, if 4 levelers
are desired, 77-119-02 becomes 77-119-024.
Because we are
a complete manufacturing facility, TMC can readily provide custom
configurations to meet your special requirements. Some of the more
common special requests we have addressed are discussed here.
Special Materials for Optical Tops, Optical Tables
Tables made of any commercially
available metallic materials are readily manufactured by TMC.
Aluminum, non-ferromagnetic 300 series stainless steel, and
thermally stable Super Invar are among the most frequent requests.
and Ports for Optical Tops, Optical Tables
Our multiple new 2,000-watt laser machining
centers coupled with our capacity to punch, drill, shear, form,
and weld steel makes inclusion of custom hole patterns readily available.
Common patterns include notches, rectangular through-holes, laser
ports, and threaded bosses.
All TMC optical tops can be supplied with
a laser port, as noted in the laser port and hole pattern suffix
The laser port is a 1 7/8 in. (47 mm) diameter
stainless steel tube running through the table, bonded to the top
and bottom skins.
Provisions for mounting a laser shelf underneath
the table top are included with this option.
By welding a precision ground and aligned joiner plate system
to the table skins, TMC can provide a rigid coupling between optical
tables. In addition to tables coupled end-to-end, we can easily
join them in “L” or “T” shapes. (Even relatively
small tables are sometimes made in sections to allow rigging in
In addition, we can provide configurations
with two working heights on one table by coupling tables of differing
All joined tables are assembled and tested
in our factory, shipped separately, and reassembled on site. The
tables can, at any time, be separated and supported individually
