Precision Lens Positioner, 0.5 in. Diameter, 100 TPI XY

The LP-05A-XY Two Axis Lens Positioner provides two degrees of precision positioning for 1/2 inch (12.7 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 2 inch optical axis height.

Two, Three or Five Axes of Positioning

Two-axis XY models have orthogonal transverse adjustments.
Three-axis XYZ models add translation along the optical Z-axis. Pure Z-axis motion without rotation of the lens is achieved through turning the knurled ring with precision 80 TPI threads.
Five-axis XYZ θXθY models provide smooth XYZ translation plus true gimbaling about two orthogonal, coplanar axes. Five independent degrees of freedom allow you to accurately position an optic in any plane along any axis.

True Gimbal Adjustments

LP-A Five-axis XYZ θXθY models provides smooth XYZ translation plus true gimbaling about two orthogonal, coplanar axes. These five independent degrees of freedom allow you to accurately position an optic in any plane along any axis.

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.
