The LP-2A-XY Two Axis Lens Positioner provides two degrees of precision positioning for 2 inch (50.8 mm) optical components. Precise, 100 TPI adjustment screws with knobs including an integral hex hole allow smooth adjustment with increased sensitivity. Our zero-free play XY mechanism ensures accurate positioning and enhanced long-term stability, without relying on grease to take up the clearance between sliding elements, thereby reducing drift over both time and temperature. Independent locks for each axis of translation securely lock the mechanism, not just the actuator screws, maintaining stable optical alignment. Engaging or disengaging each lock has negligible influence on the other axes. This Two axis XY model has orthogonal transverse adjustments. The threaded central aperture accommodates optic retaining rings and a variety of optics holders for simple lenses, objective lenses, or other optics. Each unit is supplied with two non-marring Delrin retaining rings as well as an optic holder. All LP Series Lens Positioners can be bolted down to a table using the slotted base plate included which attaches to either side of the mount. Both English and metric threaded holes in the bottom allow for post mounting, providing easy adjustment of their optical axis height and azimuthal orientation. It has a 3 inch optical axis height.

LP-2A-XY二轴透镜定位器为2英寸(50.8 mm)光学元件提供了两种精度定位。精确，100 TPI调整螺丝与旋钮，包括一个完整的六角孔，允许光滑的调整与增加的灵敏度。我们的零游隙XY机构确保了精确定位，增强了长期稳定性，不需要依靠润滑脂来占据滑动元件之间的间隙，从而减少了随时间和温度的漂移。各轴独立锁紧机构，安全锁紧机构，不只是执行机构螺丝，保持稳定的光学对准。每个锁的接合或分离对其他轴的影响可以忽略不计。这个两轴XY模型具有正交的横向调整。螺纹中心孔可容纳光学固定环和各种光学支架，用于简单透镜、物镜或其他光学。每个单元提供两个非马氏体德林保持环以及一个光学支架。所有LP系列镜头定位器都可以用螺栓固定在一个表上，使用附带在支架两侧的开槽底板。底部的英制螺纹孔和公制螺纹孔都允许安装后，便于调整光轴高度和方位。它有3英寸的光轴高度。
