Description
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 all-steel construction, excellent thermal stability, and broadband damping optimized for each table size. The 5 mm thick stainless steel top and bottom skins have a matte finish and the top skin is precision-machined with a 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.
