Brand: ThorLabs | Category: Scientific & Laboratory Equipment

SM1 threaded lens tubes that take one inch optics directly and build light-tight optical subassemblies. The 1.035 inch-40 thread standard runs through most of the Thorlabs range, so tubes, mounts, adapters and cage plates all interlock.

Lens tubes that translate an optic along the optical axis inside an SM1 assembly. Rotating versions give simple travel while the SM1ZM and SM1NR zoom housings use a helical drive so the internal cell moves without rotating, which matters for polarisation optics.
One piece non-magnetic stainless steel posts, precision ground to 25.0 mm diameter and tapped at both ends so they stack. The pedestal base works with clamping forks, giving a rigid way to set optic height on a table or breadboard.
Extruded aluminium rails with a 25 mm square profile and channels on all four faces, used to build enclosures, frames and rigid mechanical structures on an optical table. T-nuts in the channels accept any 8-32 or 1/4 inch-20 optomechanical component.
