The Newport 440 Linear Stage is a precision positioning instrument featuring micrometer-head actuation for single-axis (X) motion control. Engineered with stainless steel or aluminum construction and ball bearing guidance, this stage delivers 1 µm sensitivity with 20 µm graduation increments. It maintains angular deviation of <200 µrad pitch and <150 µrad yaw, ensuring straightness and repeatability in laboratory, research, and industrial metrology applications. The modular design accommodates stackable configurations for multi-axis setups and integrates with optical tables via slotted base plates.
