Optical Tables, Breadboards, Microscopy Workstations – Custom Designs or Standard Sizes – Delivered Faster and Cheaper!
An optical table is a vibration isolated platform specially designed for highly sensitive applications prone to vibrations such as high-resolution spectroscopy, microscopy, precision nanostructure studies, and various optics, photonics, and metrology experiments.
The primary goal of an optical table is to minimise relative motion between components placed on the surface of the optical table top. We offer optical tables with both active and pneumatic vibration isolation solutions for various application requirements.
Active Isolation Optical Tables
DVIA-MO series combines optical breadboards/granite surface plates and DVIA-M active isolators to create the ultimate hybrid active optical tables, offering superior vibration isolation in low-frequency range for the most challenging applications such as high-resolution spectroscopy, microscopy, precision nanostructure studies, and fabrication.
It consists of four active vibration isolators incorporated with elements of active systems that enable feedback and feedforward control mechanisms. Inertial sensors and actuators detect and control vibrations in all six degrees of freedom (three translational degrees of motion (X, Y, and Z), and three rotational degrees of motion (pitch, roll, and yaw), reducing vibrations in the 1-10 Hz range. Meanwhile, the passive isolation system can support massive payloads of up to 6000 kg and provides vibration isolation also in the high frequency range.
Pneumatic Optical Tables
We use the term Pneumatic Isolation to refer to passive isolation systems with automatic levelling capabilities. In pneumatic optical tables, the relative motion between components placed on the table is minimised by the following features:
- Pneumatic Isolators:
Pneumatic Isolators designed with low natural frequency minimise the transmission of floor vibrations to the tabletop. They also provide effective damping of the vibration amplitudes caused by resonance, assuring system stability and fast settling times. - High Dynamic Rigidity:
An optical table top with high dynamic rigidity dampens and resists deflections caused by floor vibrations, acoustic noise, and mechanical sources on the surface that may pass through pneumatic isolators. - High Static Rigidity:
An optical table top with high static rigidity minimises the relative motion between the individual components placed on top of the optical table, thereby maintaining high system performance. High static rigidity also increases the natural frequency of the table top which prevents the simultaneous occurrence of low-frequency vibrations that are not reduced by isolators.
Custom Optical Tables
Pneumatic Optical tables consist of two parts – the Table Tops and Table Supports. Our lightweight, incredibly rigid steel honeycomb Table Tops and Breadboards are combined with uniquely designed pneumatic and rigid support frames, significantly reducing vibrations and relative motion between components. Additional accessories for customisable geometries are also available. Our joined table systems enable multiple tables to be joined end-to-end, side-to-side, side-to-end, or mixed configurations to form long and wide “U”, “L”, “T”, or “Cross” shaped tables.
How to Order
Different combinations are available to suit a variety of experimental requirements and space availability in the laboratory. Optical Tables can be ordered by specifying the following information:
- Table Top type and dimensions
- Total table height
- Table Support type and size
- Table Accessories (optional)
A much wider range of Optical Table sizes than other suppliers is available. We substantially study customers’ requirements in order to provide the right isolation options for optical tables. Please contact us to obtain information on product specifications, requirements and applications.
DVIO-S Series: Optical Table Supports
Vibration isolators for optical tables are designed to have a low natural frequency so that ambient vibrations from the floor can be filtered before they reach the optical table top and cause relative motion between components on the surface.
DAEIL offers two types of optical table supports – pneumatic isolators and rigid non-isolators. Our pneumatic isolators provide industry-leading vibration isolation performance and exceptional damping via the dual-chamber design. Rigid supports are used for equipment requiring rigid platforms with no vibration isolation systems.
The table supports are available in Tie-Bar and Self-Standing configurations.
Pneumatic Supports
Our pneumatic supports achieve vibration isolation in the low-frequency range (1-10 Hz) and offer the following features:
- Dual chamber design – effective damping:
Each pneumatic isolator consists of two chambers that are uniquely designed and developed to lower the natural frequency. This design provides very strong damping for large displacements of the piston and less for small displacements. This allows for fast settling of the payload, without compromising small amplitude vibration isolation performance. - Pendulum piston for superior vibration isolation:
Our unique design of the piston and gimbal support forms a frictionless pendulum system to provide horizontal isolation and damping of very low-frequency vibrations. The optimised air chamber is sealed with an ultra-soft rolling diaphragm and the piston, softening the stiffness to improve the vertical vibration isolation performance. - Automatic levelling system – levelling valves:
The high-performance levelling valves automatically re-level an optical table top with multiple options for levelling repeatability (±0.05 mm to ±1.0 mm) as required by the application.
Tie-Bar Type
Pneumatic isolators are integrated into a tie-bar frame by welding. Levelling feet and casters are mounted to the tie-bar, providing mobility and easy installation.
We offer a wide variety of support frames with customisable dimensions and load capacities ranging from 300 kg to 2000 kg.
Self-Standing Type
4, 6, or 8 self-standing supports can be installed according to application requirements. We offer supports with standard dimensions and load capacities ranging from 500 kg to 3000 kg.
Rigid Supports
Tie-Bar Type
Rigid supports integrated into tie-bars with casters provide high load capacities, mobility, and easy transportation at affordable prices. Rubber pads mounted on rigid isolators offer a basic vibration isolation where customers’ applications are not sensitive to vibrations.
Self-Standing Type
4, 6, or 8 self-standing supports can be installed according to the payload and dimensions of the table top. We offer supports with standard dimensions and two different payload capacities – 1700 kg and 2500 kg. Custom configurations are available upon request.
We substantially study customers’ requirements in order to provide the right isolators. Contact us for queries regarding products and applications.
DVIO Series: Optical Table Accessories
Overhead Shelf (DOTS)
Overhead Optical Table Shelf Systems are free-standing systems designed to maximise laboratory space for instruments. The height of the hanging shelves is adjustable and provides increased table space and a convenient location for instruments such as oscilloscopes, power suppliers, controllers, laser diode drivers, etc.
These systems have the following features:
- Adjustable height hanging shelves.

- The system is made up of steel with a black powder coat finish.
Optical Table Enclosure (DOTE)
The enclosure for the optical table is made of a durable aluminium frame and acrylic panel to protect the equipment from acoustic noise heat, light, and air currents. The aluminium frame can be either directly mounted on optical table tops or free-standing on floors. Hinged or sliding doors, overhead shelves, and wire hole options are available. Custom dimensions and configurations are available upon request.
Joined Table System
Multiple optical tables can be joined to form longer and wider tables that enable users to have larger sizes of tables in various geometries to meet complex beam-path requirements and other scientific needs. Joined table systems have the following features and advantages:
- Table tops with different thicknesses can be coupled to provide work surfaces with different heights.
- Ideal for large and multiple optical tables that are difficult to move around or install.
- All joined optical tables are delicately pre-assembled and inspected at our factory to ensure the damping, stiffness, and flatness are maintained across the joined tables.
- Individual tables are assembled and tested to confirm the specifications, and shipped as dismantled tables for on-site assembly.
The tables can be coupled end-to-end, side-to-side, and/or side-to-end as shown below. Custom configurations are also possible.
