The Newport Precision Adjustment Screw Model AJS100-2 delivers sub-micron positioning sensitivity for optical and mechanical alignment systems where fine-tuning without position readout is required. Built with precision-rolled stainless steel threads and an aluminum-bronze collet, this adjustment screw provides smooth, stictionless movement across a 50.8 mm travel range. The 100 TPI thread pitch enables 0.71 µm sensitivity per revolution, supporting rapid alignment cycles while maintaining the axial load capacity of 90 N. A patented non-influencing side lock secures position without affecting adjustment repeatability.
