The Newport 430 Linear Stage Positioner delivers precise, repeatable linear motion control in a compact, low-profile form factor. Built with steel construction for high stability and rigidity, this stage employs ball bearing guidance to ensure smooth travel across its full range of motion. The 4″ × 3″ platform stands approximately 1″ in height and accepts standard 1/4-20 tapped hole mounting, making it ideal for optical bench integration and mechanical system assemblies. Travel range extends from 1″ to 2.5″ depending on configuration.
