Laser Shelves

TMC tables larger than 36 in. x 72 in. (900 x 1800 mm) and supported at least 18 in. (450 mm) above the floor can be fitted with a laser shelf. The shelf consists of an additional undrilled 2 in. (50 mm) thick breadboard attached to the bottom plate of the table. Though such a support system will not match the performance of direct mounting of equipment to the table’s top surface, for less sensitive applications this arrangement can save valuable working space on the top. In some cases, our tiebars may interfere with shelf mounting. Contact us if you are in doubt.

  Enclosures

   TMC manufactures two types of environmental
   enclosures to provide draft, dust, light, and
   acoustic isolation for optical tables.

  Caution! The enclosures are not designed
  to protect eyes from laser hazards.

Free-Standing Enclosure.

A floor-mounted frame with removable, soft vinyl sidewalls. The panels are opaque with the exception of transparent panels along the front side. This enclosure is designed for tables with an operating height of 36 in. (900 mm). Since this enclosure does not contact the table, it does not compromise any of the table’s damping or isolation performance. This enclosure is also available with a special construction of either all transparent or all opaque panels.

Table-Top Enclosure

Consists of a frame mounted directly to the table top. The side panels are a clear acrylic sheet construction and mount in sliding tracks. “Smoked” panels are available as a special option in place of the clear panels. In addition, an air blower/filter is available with this enclosure as an option, mounted to a side panel for additional dust protection. This is not recommended for vibration isolation systems.

Earthquake Restraint System

TMC’s earthquake restraint bracket system provides increased safety and stability for optical tables in high-risk earthquake areas without affecting table performance.

The TMC earthquake restraint system relies on top brackets and upper tiebars to control motion of the table top and, where severe occurrences are anticipated, floor brackets with lower tiebars to secure the support structure to the floor. Under normal conditions, there is no contact between the top brackets and the support structure, so that performance of the optical top and the vibration isolation system are not affected. Clearances are large and brackets are lightweight, stiff, well-damped, unobtrusive and encapsulated with soft elastomer to provide gradual snubbing.

Our earthquake restraint bracket system can be retrofitted to an installed TMC optical table or specified with a new order.

Inferior, competitive designs may depend on large, pendulum-like structures that hang below the table top and connect to the floor. Since pendulums characteristically have low resonant frequencies, these add-on structures lower the resonant frequency of the table top and degrade compliance and damping. In addition, the floor connection creates a potential rigid coupling between table top and floor, which can compromise vibration isolation if it drifts out of calibration.

Floor Restraint Brackets

Floor brackets are recommended where quakes are anticipated. They encircle the lower tiebars close to the support posts and bolt to the floor (see illustration). Four brackets are usually recommended. Since standard TMC post-mount support systems are supplied with only upper tiebars, an additional set of four lower tiebars must be specified for both new and retrofitted orders. Specify both floor brackets and tiebars individually.
Back

Upper and Lower Tiebars

Standard post-mount support systems are supplied only with upper tiebars. An additional set of lower tiebars is required when floor restraint brackets are used; or, you may want an additional row of tiebars for extra strength. Tiebars must be specified individually - see ordering chart.
