Newport RPR-48-8 Reliance Optical Table Breadboard 4x8 ft 8in 1/4-20 1in Grid

Newport RPR-48-8 Reliance Optical Table Breadboard 4x8 ft 8in 1/4-20 1in Grid

The Newport RPR-48-8 is a heavy-duty optical table from Newport's RP Reliance series, designed for industrial and educational optical and photonics lab setups. It measures 4 ft × 8 ft (48 × 96 in) with an 8-inch overall thickness, and features a 400-series ferromagnetic stainless steel top surface with sealed 1/4-20 (M6) threaded mounting holes on a 1-inch grid — the standard layout for mounting Newport and compatible optical components, posts, bases, and fixtures.

Applications

Optical tables like the Newport RPR-48-8 are the core work surface in photonics, laser, and optics laboratories. They provide a flat, vibration-damped platform for building and aligning optical systems — laser setups, interferometers, beam-steering assemblies, spectroscopy systems, and microscopy rigs. The 1/4-20 threaded hole grid on a 1-inch pattern is the standard layout used across Newport's breadboard and optical component ecosystem, making this table compatible with the vast majority of Newport posts, bases, clamping forks, and third-party optical hardware. The RP Reliance series targets industrial and educational settings where broadband vibration damping and high static rigidity are needed but the extreme isolation performance of Newport's premium RS Series is not required. These tables are widely used in university physics and engineering labs, industrial R&D environments, laser manufacturing facilities, and photonics product development — anywhere a stable, repeatable optical build surface is needed at a practical price point. The sealed-hole design keeps the threaded inserts clean and free of debris, extending the usable life of the mounting surface.
