Precision Lens Positioner, 2.0 in. Diameter, 100 TPI XY

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. 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.

Independent Non-influencing Locks

Independent locks for each axis of translation and rotation 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.

Table or Post Mounting

The LP Series Lens Positioners can be mounted to optical tables directly with the slotted base, or to an optical post using the threaded holes at the bottom.

Modular Slotted Base and Riser

When the space to mount a lens positioner within an optical system is limited, the slotted base of all LP Series Lens Positioners can be removed to reduce their footprint. For OEM systems with a lower optical axis height, the riser piece of the two-axis XY models and three-axis XYZ models can also be removed, with the smaller tapped holes on the back side of the lens positioner accessible for mounting. (Note that the riser piece of the five-axis models is not removable.)
