The Concept of Closed Top Tables.

Real Closed Top. No way for liquids or tiny particles to get in. There are only the holes you do use. Make "new" holes by yourself. If You need a hole, clear it of the plug with a pencil or any similar item. Seal the no longer needed hole with the self-solidifying plastic mass again. To close the holes that are not in use we pre-set the plastic plugs of two colours, so that they form a coordinate grid with a mesh of 100 mm to facilitate composition of optical schemes.

Honeycomb Table Tops 1HT provide the base on which precision optical and laser work is performed. The table tops have a honeycomb core inside.

The table tops meet high requirements for rigidity, flatness, vibration isolation and damping. We work constantly to improve the design, weight and cost-effectiveness of the table tops.

Standard Honeycomb Tabletop 1HT consists of a 4-6mm thick cold-rolled stainless ferromagnetic steel top skin, and 3-6mm thick bottom skin, both bound under high pressure to a honeycomb core, using a special epoxy resin. Thickness of the skins depends on the dimensions of the table top.

The top skin has a pattern (grid) of M6 holes spaced by 25mm with ±0.1mm accuracy. It allows to make very quick experimental setups, and, at the same time, ensures a high level of precision and reproducibility. The surface of the top skin is ground to flatness of ±0.05 mm over any 1m² area over the entire surface. It is chemically passivated, ensuring a long life of the top skin. The bottom skin is coated in a firm decorative coating.

Our standard honeycomb core is made of 0.25 mm corrosion-resistant coated sheet steel. A special composition of epoxy resin guarantees adhesion, rigidity, stability and damping corresponding to highest requirements.

The side-walls of the table top are made of a special acoustically hollow plastic which damps acoustic vibrations. The side-walls are covered in a decorative black leather substitute.

Upon request a Laser Port can be embedded in the table top allowing a laser beam to be let through the table (see the end of this page).

The Honeycomb Table Tops 1HT have been mechanically and acoustically tested by qualified specialists.

Laser Ports on the Table Top are used to bring a laser beam or cables through it. The standard location is chosen for use with the Laser Shelves 1LS51/1LS52.
To specify a Laser Port in your order please append letter "H" to the code for a Honeycomb Table Top
e.g. 1HT10-20-20H
