The M-481-A-S Metric Rotation Stage is ideal for fine 5° tuning the angular orientation of any component after rotating it to an approximate angle. An inner stage rotates 360° in a precision bored bushing that locks with a side mounted thumbscrew. The outer stage is a high resolution, tangentially driven design. Scale markings indicating every degree and a vernier with 5 arc min markings are engraved on the side of the stage. The 481-A-S uses 100 pitch AJS Fine Adjustment Screws for high resolution and attaches to tables and breadboards via clearance slots in the base, and to posts using one of two tapped holes located in the side of the stage. Additionally, the M-481-A-S includes two 25.4 mm diameter retaining rings and a solid aperture insert with a centered clearance hole for on-axis mounting of components such as post holders.


m - 481 -一个度量旋转舞台是理想的好5°调优后任何组件的角定向旋转一个近似的角度。内部舞台旋转360°精密无聊衬套,锁安装翼形螺钉。外层是一个高分辨率，切向驱动的设计。舞台侧面刻有刻度标志，指示每一度，并刻有5弧分刻度的游标。481-A-S采用100节高分辨率AJS微调螺丝，通过底座的间隙槽连接到工作台和面包板上，并通过位于舞台一侧的两个抽头孔之一连接到柱子上。此外，M-481-A-S包括两个25.4 mm直径的挡圈和一个实心孔插入，该孔具有中心间隙孔，用于柱架等部件的轴上安装。
