Thorlabs' 210 mm (8.3") thick Nexus™ optical tables are offered in a variety of lengths and widths from 3' x 6 ' (1 m x 2 m) to 4.8' x 8' (1.5 m x 2.5 m). They feature excellent thermal stability and broadband damping optimized for each table size. The 5 mm thick stainless steel top and bottom skins have a precision-machined matte finish with surface flatness of ±0.1 mm over any 1 m2 area. The table has sealed 1/4"-20 (M6) mounting holes on 1" (25 mm) centers with a 0.5" (12.5 mm) border at the edge of the table.

Virtually Nonmagnetic Construction
These optical tables are constructed of 304L grade stainless steel. This alloy of steel contains less iron than typical stainless steel, which reduces its ferromagnetic properties. 304L steel is usually referred to as "virtually nonmagnetic" since weak magnetic properties are still present.

Nonmagnetic optical tables are built to order with a typical lead time of 4 - 6 weeks. Custom sizes and options are also available with a typical lead time of 6 - 8 weeks. See the Nexus Guide tab for a complete overview of the Nexus optical tables product line.


Our Mission is to accelerate the advancement of optical technology for precision measurements and their applications from the table tops of research laboratories to standard use in communication and high technology industries. Our aim is to serve our customers. Our hope is to create a place for highly skilled people in an open environment
