The ALM-2A Precision Adjustable Lens Mount allows 25.4 to 60.0 mm diameter optics to be precisely centered in a beam then easily removed and replaced with excellent repeatability. Lenses can be precisely located within a range of +/- 2 mm by three 40-TPI stainless steel shaft assemblies, two rigid and one spring-loaded; each has removable Delrin V-groove tips. Installing optics is easy. Set the two rigid steel shafts to the desired radius, insert your element and adjust the spring loaded shaft until the optic is held securely in place. In addition to the snap-in V-groove tips for mounting thin optics, a set of L-shaped tips for mounting thick lenses, mirrors and beamsplitters is also included. The spare tips are conveniently stored on the outer diameter of the ALM housing. Long objects, like cylindrical laser heads, can be supported using two ALM Series mounts. The ALM Series Lens Mounts incorporate a counter bored clearance hole in their base that is compatible with both 8-32 and M4 screws. This allows for easy attachment to English or Metric SP and MSP Series posts, as well as Newport’s PS Series pedestal posts. The ALM-2A has a 38.1 mm axis height.

ALM-2A精密可调透镜支架允许25.4到60.0毫米直径的光学元件精确地集中在光束中心，然后很容易地拆卸和更换，具有良好的重复性。镜头可以精确定位在+/- 2mm范围内，通过三个40-TPI不锈钢轴组件，两个刚性和一个弹簧加载;每个都有可移动的Delrin v型槽尖端。安装光学元件很容易。将两个刚性钢轴设置为所需的半径，插入元件并调整弹簧加载轴，直到光学元件安全到位。除了用于安装薄光学的插入式v槽尖端，还包括一组用于安装厚透镜、镜子和分光镜的l形尖端。备用的尖端方便地储存在ALM外壳的外径。长对象，如圆柱形激光头，可以支持使用两个ALM系列安装。ALM系列镜头支架在底座上有一个与8-32和M4螺丝兼容的反钻孔间隙孔。这允许容易连接到英语或公制SP和MSP系列柱，以及新港的PS系列底座柱。ALM-2A轴高38.1毫米。
