Variable Size Lens Mount, 25.4-60 mm, 40 TPI XY Adjusters

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.
